Protimeter MMS2 Instruction Manual
1. Introduction
The Protimeter Moisture Measurement System2 (Protimeter MMS2) is a
powerful and versatile instrument for measuring and diagnosing dampness in
buildings and building materials. This product enables building surveyors and
other practitioners to measure moisture levels of building elements such as
walls, floors and building environments simply by switching between the five
different modes of operation. In this way, a detailed understanding of the
moisture condition of the property can be obtained.
2. Safety Considerations
• Caution note for the WME pins - The Pin Moisture measurement pins are
extremely sharp and the instrument should be handled with due care. The
pins should be covered with the cap provided with the unit when the
function is not in use.
• IR temperature measurement - Please note that the readings are indicative
readings outside the measurement range of the IR temperature mode and
the accuracy of the measurement is not guaranteed outside the range.
• Calibration of unit - The accuracy specifications of the product are valid
for one year after the date of calibration, and the product requires
recalibration after this period.
Laser pointers are effective tools when used properly, but the following
considerations must be observed when using laser pointers:
• Never look directly into the laser beam.
• Never point a laser beam at a person.
• Do not aim the laser beam at reflective surfaces.
• Never view a laser beam using an optical instrument, such as binoculars
or a microscope.
2. Safety Considerations (cont.)
INS8800 Rev. C 1
Page 8
Protimeter MMS2 Instruction Manual
• Do not allow children to use laser pointers unless under the supervision of
an adult.
• Use only laser pointers meeting the following criteria:
• Labeled with FDA certification stating “DANGER: Laser Radiation”
for Class 3R lasers or “CAUTION: Laser Radiation” for Class 2
lasers.
• Classified as Class 2 or 3R according to the label. Do not use Class 3b
or Class 4 products.
• Operates at a wavelength between 630 nm and 680 nm.
• Has a maximum output less than 5 mW, the lower the better.
3. Product Components and Accessories
The MMS2 instrument measures the different parameters in the buildings:
room temperature, room humidity, building material moisture, surface
moisture and surface temperature (contact and non-contact method). To
measure all the above mentioned parameters, MMS2 uses different sensors,
along with a variety of accessories for convenient measurements. The
following external connections are found on the instrument (see Figure 1 on
page 3):
A - This edge connection socket is for use with a Hygrostick
Short Quikstick probe.
B - This jack connection socket is for use with a moisture probe, deep wall
probes or a Hammer electrode.
C - This jack connection socket is for use with the Direct Contact Surface
Temperature Sensor.

4. MMS2 Modes
The Protimeter MMS2 can be used to detect and measure moisture in
non-conductive solid materials such as wood, drywall and masonry. The
MMS2 can measure the different parameters in building applications: room
temperature, room relative humidity, surface temperature with contact and
non-contact method, qualitative measurements and precise and localized
moisture content measurements in wood or WME values in materials other
than wood.
4.1 Pin Moisture Meter - Selection and Use
Navigate to SELECT MODE -> PIN MOISTURE METER and press to select the
Pin Moisture Meter mode. Connect the moisture probe, deep wall probe, or
Hammer electrode into socket B of the MMS2 instrument.
The instrument can now be used to take actual
%MC (moisture content)
readings in wood and %WME readings in non-conductive solid materials other
than wood by placing the moisture probe pins in firm contact with the surface
as shown in Figure 2 on page 6. The measured value is displayed and the
progress bar indicates whether the material is in a DRY, AT RISK or WET
condition.

When the instrument is in Pin Moisture Meter mode, by default it displays
WME WOODTYPE A (see the Protimeter wood calibration chart).
Use the up and down buttons / to navigate between different
wood types. From Wood Type B to Wood Type H, if MC% is greater than
ABOVE FIBER SAT will be displayed as the wood status, otherwise the
30.0,
wood status will not be displayed. When using the built-in pins, the operator
should make firm contact on the surface. It is not necessary or recommended
to push the pins deeply below the surface.

Protimeter MMS2 Instruction Manual
4.1a Using Auxiliary Deep Well Moisture Probes in Measure Mode
To take sub-surface readings in masonry, the deep wall probes should be used
instead of the standard moisture probe. To use the deep wall probes, drill two
1/4” (6 mm) diameter clearance holes, spaced 2-3 in. (50-75 mm) apart, to the
required depth. Push the two deep wall probes into the holes and press and
hold the tips firmly against the bottom of the holes. Ensure that the probes are
connected to socket B and measure the %WME value as described in
Section 4.1, “Pin Moisture Meter - Selection and Use”, on page 5.
Note: The most convenient way to take sub-surface readings in wood is by
using an optional Hammer Electrode.
4.1b Detecting Hygroscopic Salts
The Protimeter MMS2 instrument can be used as a basic salts detector when
used with the moisture probe, filter papers and distilled water (not included).
Moisten the filter paper with the water and take a reference reading across it
with the moisture probe. Then place the moistened filter paper against the
surface of interest and hold in place for 30 seconds. Remove the paper and
place the pins of the moisture probe across the paper again and observe the
reading. Compare this reading with the original reference reading. If the
difference is more than 20 points, there is significant salts contamination that
may warrant further investigation.

4.2 Pinless Moisture Meter — Selection and Use
Navigate to SELECT MODE -> PINLESS MOISTURE METER and press to
select the Pinless Moisture Meter mode.
The instrument can be used to take relative moisture readings in solid,
homogenous materials (such as walls and floors) by holding the surface of the
sensor bulge against the surface (see Figure 3 below). Relative readings
ranging from 60-999 appear on the LCD together with a progress bar that
indicates whether the material is in a

8 INS8800 Rev. C
Page 15
Protimeter MMS2 Instruction Manual
4.2 Pinless Moisture Meter — Selection and Use (cont.)
As reliable readings are obtained only if the sensor bulge is in direct contact
with the surface, the Search mode is not suitable for surveying textured
finishes. The nominal depth of penetration is up to19 mm (3/4”) in dense,
homogeneous materials. Readings taken through low-density coverings
(carpets, polystyrene tiles, etc.) will not be representative of the moisture level
in the substrate itself. When using the MMS2 in Pinless mode, it is
recommended that no attachments are connected. This practice will minimize
reading errors and the potential for electromagnetic interference with other
electronic equipment. When the Pinless Moisture Meter mode is selected, the
device will display the surface moisture in terms of Wood Moisture
Equivalent count.
Note: Place the MMS2 on the surface, but do not slide it. Sliding will wear
out the back of the meter, as well as possibly mark the wall.

4.2 Pinless Moisture Meter — Selection and Use (cont.)
In Search mode, the device has the capability to give comparative
measurement.
Note: If metal is present below the surface, the MMS2 may give a false
positive.
Comparative measurement helps in measuring whether the surface
moisture/material is wetter or dryer than the Reference surface/ material. If
the surface moisture/material is wetter than the reference surface/ material,
then the progress bar is red, or if it’s dryer, then the progress bar is green.
This method takes four steps:
1. Select Pinless Moisture meter under the Main Menu.
2. Place the device on the material which has been chosen as the reference
material.
3. Press the right arrow button for two seconds to store the reading as
reference reading.
4. Now if the device is placed on any material, it indicates whether the
material is wetter or dryer than the reference material.
4.3 Hygrometer - Selection and Use
Navigate to SELECT MODE -> HYGROMETER and press to select the
Hygrometer mode.
To use the Protimeter MMS2 as a Hygrometer (see Figure 4 on page 11),
connect the Hygrostick, Quikstick or Short Quikstick probe into socket
either directly or indirectly with the extension lead.

Page 17
Protimeter MMS2 Instruction Manual
4.3 Hygrometer - Selection and Use (cont.)
Relative humidity and temperature measurements are made with the
Hygrostick, Quikstick or Short Quikstick probe, and the MMS2 instrument
uses these values to calculate a range of psychometric readings. When using
the MMS2 to measure the conditions in air, the humidity probe is normally
connected directly to the instrument. However, when it is impractical or
awkward to use the instrument in this way, the extension lead may be used to
connect the Hygrostick, Quikstick or Short Quikstick to the instrument.
Typically, the extension lead will be used when taking readings from probes
that have been embedded in structures such as walls and floors.

5. Diagnostic Procedure Guidelines
When diagnosing dampness in buildings, three key criteria must be
considered, as outlined in Table 5 below.
Table 5: Diagnostic Criteria
Item Criteria Notes
1 Is a wall or other
building element in
a safe air-dry
condition?
2 Is the surface
temperature of a
wall or other
building element
above or below the
dew point?
3 Is a wall surface or
other building
element
contaminated with
hygroscopic salts
or other conductive
material?
Air-dry is the moisture content that is normal
and safe (from moisture-related deterioration or
decay) in buildings. When the Protimeter
MMS2 moisture meter modes are selected,
measured values are identified as
DRY, AT RISK
or WET.
Dew point is the temperature at which a given
quantity of air becomes saturated (100% RH)
and forms dew, or condensation. If a surface is
colder than the dew point, condensation occurs.
When the Protimeter MMS2 Condensator Mode
is selected to measure TDIFF (the proximity of
a surface to the dew point) the instrument
identifies either a NO CONDENSATION condition,
an AT RISK condition, or a CONDENSATION
occurring condition.
Artificially high moisture meter readings may
be obtained either in material that has been
heavily contaminated by hygroscopic salts or in
materials that are conductive by nature. The
presence or absence of nitrates and chlorides
should be established when investigating
suspected rising dampness situations in
particular.
20 INS8800 Rev. C
Page 27
Protimeter MMS2 Instruction Manual
5. Diagnostic Procedure Guidelines (cont.)
Item 1: The Search and Measure modes (pinless and pin) should be used in
combination to map out the extent of a moisture problem and to distinguish
between surface and sub-surface moisture. The profile of readings obtained
will give insight into the potential cause (e.g., condensation, lateral ingress or
rising dampness) of a moisture-related problem.
Far greater insight will be obtained from moisture readings taken in a
methodical manner than from those taken in a random manner. When testing
walls, the user should start by taking readings at the lower levels and move up
the wall in regular steps of 4-6 in. (10-15 cm). When high subsurface relative
readings are obtained in the Search mode, the user is strongly recommended
to quantify these values in %WME terms by using the deep wall probes in the
Measure mode. If the depth of clearance holes is increased incrementally by a
nominal 0.4 in. (10 mm) at a time, the moisture profile through the wall can be
established.
Item 2: Condensation related moisture problems are common. When assessing
the risk of condensation, or confirming its existence, the proximity of the
actual temperature of the surface under investigation to the dew point must be
established. The TDIFF measurement in CONDENSATOR mode tells the user
how many degrees the temperature of a surface is above or below the dew
point.
As many condensation situations are transient, TDIFF readings should be taken
in a methodical and regular manner, similar to moisture meter readings in
materials. Ambient RH and temperature values should also be taken to assess
the moisture condition of the room as a whole. Dwellings and working
environments generally have an RH from 40% to 60%, so there may be cause
to investigate environments that register RH values outside this range.
INS8800 Rev. C 21
Page 28
Protimeter MMS2 Instruction Manual
5. Diagnostic Procedure Guidelines (cont.)
Item 3: Two hygroscopic salts, chlorides and nitrates, may build up on the
surface of walls where rising dampness or wicking occurs. As groundwater
moves through the wall and migrates to the surface, salts tend to accumulate
where the rate of evaporation of this water is greatest. The salts themselves
are non-conductive, but when mixed with a small amount of moisture a highly
conductive solution is formed. The presence (or absence) of such salts should
therefore be established when rising dampness is suspected by using the
Protimeter MMS2 in Measure mode as described. When required, the
Protimeter Salts Analysis Kit (part number BLD4900) can be used to identify
the relative concentrations of nitrates and chlorides.
In summary, effective dampness diagnosis is a process that draws on the
knowledge and expertise of the surveyor. The Protimeter MMS2 kit enables
the user to investigate moisture levels in materials and environments from
various perspectives that, in turn, permits a more thorough and reliable
judgment as to the cause of dampness related problems.
6. Calibration Checking
Check the moisture meter Measure Mode by holding the pins of the moisture
probe across the exposed wires of the calibration check device (Calcheck).
The WME value of correctly calibrated instruments is 17-19. Instruments that
register values outside this range should be returned to Protimeter for
servicing.
Note: Search mode can be checked against a stable area of wall. For
comparative purposes, humidity and ambient temperature conditions
should be stable and consistent.
Working Hygrostick, Quikstick and Short Quikstick probes can be checked
against reference probes and/or over standard salt solutions.
22 INS8800 Rev. C

7. Care and Maintenance
The Protimeter MMS2 is a precision-built electronic instrument that will
provide many years of reliable service if the following points are observed:
• When not in use, keep the MMS2 instrument and its accessories in the
factory carry case. Store the case in a stable, dust-free environment and
keep it out of direct sunlight.
• If the instrument is to be stored for more than four weeks or if the low
battery power symbol appears on the display, remove the batteries from
the instrument.
• When using the MMS2 in Search mode, do not slide the bulge across
surfaces, as this may lead to rapid instrument case wear. The instrument
should be lifted and placed in position to prevent such wear.
• Check the condition of the MMS2 accessories on a regular basis, and
replace them if they become worn or damaged.
• To preserve their calibration characteristics, Hygrostick probes should not
be exposed to saturated environments. If this is unavoidable, Hygrostick
probes should be replaced on a regular basis and their calibration should
be checked frequently.
