Safety Information
Read the instruction manual thoroughly to familiarize yourself with the test procedures before you begin.
Make note of any precautions in the instructions.
Read the labels on all LaMotte reagent containers prior to use. Some containers include precautionary notices
and fi rst aid information. Certain reagents are considered hazardous substances and are designated with a * in
the instruction manual. Material Safety Data Sheets (MSDS) are available at www.lamote.com. Read the MSDS
before using these reagents. Additional emergency information for all LaMotte reagents is available 24 hours
a day from the Poison Control Center listed in the front of the phone book. Be prepared to supply the name and
four-digit LaMotte code number found on the container label or at the top of the MSDS. LaMotte reagents are
registered with a computerized poison control information system available to all local poison control centers.
Keep equipment and reagent chemicals out of the reach of young children.
Protect Yourself and Equipment: Use Proper Analytical Techniques
Testing Hints
1. 2. 3.
Tightly close all
reagent containers
immediately after
use. Be sure not to
interchange caps
and pipets from
different containers.
Avoid
prolonged
exposure of
equipment
and reagents
to direct
sunlight.
Protect reagents
and components
from extreme
heat and cold.
4. 5.
Wipe up any reagent chemical
spills, liquid or powder, as
soon as they occur. Refer to
label and accompanying
MSDS for proper
reagent disposal.
4
Use care when dispensing or
handling all reagents due to
safety reasons. Some
chemicals also may cause
permanent stains if spilled.
Page 5
ANALYTICAL TECHNIQUE
1. Clean glassware is a must for accurate results. Thoroughly rinse
test tubes before and after each test. Caps and stoppers should
also be cleaned after each use.
2. Use test tube caps or stoppers, not your fi ngers, to cover test
tubes and fl asks during shaking or mixing.
3. When adding sample to calibrated test tube, be sure vial is fi lled
to the appropriate mark. The bottom of the liquid (meniscus)
should be level with the desired mark. (Figure 1)
4. When dispensing reagents from bottles fi lled with dropper plug
and cap, be sure to hold bottle vertically and gently squeeze to
dispense the appropriate number of uniform drops. (Figure 2)
5. For those reagents to be added with the screwcap pipet assemblies
enclosed, remove polyseal cap on bottle and replace with the
screwcap pipet.
NOTE: Place the polyseal caps back on the reagent bottles for
longer periods of storage. Be sure that both pipet assemblies
and polyseal caps are thoroughly cleaned before placing on
bottles to avoid contamination.
6. When dispensing reagents from pipets, hold pipet vertically
to assure uniform drop size. This is extremely important when
performing drop count titrations. (Figure 3)
7. To fi ll pipets, squeeze rubber bulb and immerse into reagent.
Release bulb to fi ll. (Figure 4)
8. To add tablets, place over test vial with silver plastic side facing
up. Press tablet through the foil into the tube. (Figure 5)

Model S and DuoSoft Softeners
INTRODUCTION
The Model S and the DuoSoft Water Softeners are designed to produce high quality softened water. As water
passes through the Model S chamber, the resin column causes scale-forming calcium and magnesium ions to be
exchanged for non-scale-forming sodium ions. When the resin is exhausted it must be replaced or regenerated.
Inexpensive
In the DuoSoft, water passes through both chambers and will be treated by both types of media. The two chambers of the DuoSoft may be easily fi lled with the media of choice for specifi c problem water.
NOTE: These softeners DO NOT yield water suitable for drinking .
READ INSTRUCTIONS BEFORE USE.
resin refi ll packages are available, or the original resin can be regenerated by chemical treatment.

Soap Demonstration
Calcium and Magnesium ions present in a water supply are the principle contributors to the total hardness.
Hard water tends to consume excessive quantities of soap and forms curds and deposits on glassware, fabrics, etc.

Precipitation Demonstration
Again, Calcium and Magnesium ions are the major contributors to water hardness. The chemical reagents in this
demonstration pull the Calcium and Magnesium ions out of solution to form a cloudy precipitate in hard water.
The water that has been run through the ion exchange column has had these ions removed, therefore, the sample
should remain clear.
NOTE: This portion of the AT-38/40 Water Quality Demo Kit is ONLY a visual demonstration illustrating the
removal of Calcium and Magnesium ions from tap water after treatment by the ion exchange process. The
results should not be interpreted beyond the intent of the demonstration.

User Tips
Testing Tips
• Read all instructions before testing.
• If not testing all tests in the sequence, follow
blanking procedure and then press button
until desired test factor is shown. Follow test
procedure.
• In one complete inversion, the tube will be
turned cap down and then right side up. The air
bubble will move slowly to the bottom of the
tube and back again to the cap end.
• If small bubbles form after adding reagents,
tap bottom of tube sharply once or twice to
dislodge bubbles. Bubbles will interfere with
the test results.
• Be sure the outside of the tubes are dry before
putting them into the ColorQ. This is best
accomplished by dispensing the water sample
from the sample bottle.
Low pH Low pH levels can signifi cantly
lower the hardness results.
Error Messages
Er 3 = Insuffi cient light is reaching the detector.
Sample may be too dark, or tube may be in
sideways. Turn off meter and retest.
Er 7 = The blank was not properly set. Turn
off meter and retest blank making sure the black
arrow on the tube is facing forward, toward the
user (not left or right).
SUN = Extremely bright sunlight is penetrating
the chamber. Turn your back to the sun to shade
the meter from bright sunlight.
Lo = Result is below the effective measuring
range for the system (e.g. < 4.0 pH for Code
7059 reagent.)
Hi = Result is above the effective measuring
range for the system (e.g. >9.0 pH for Code 7059
reagent.)
bAt = Battery is low.
Maintenance
• Clean ColorQ optics with a damp cotton swab.
Avoid abrasive cleaners that can damage
plastic.
• Replace stained or scratched tubes (0201).
Battery Replacement
Use a small Phillips head screwdriver to remove
all 5 screws in the base. Gently pull the battery
holder from the inside and replace TWO AA
style batteries. Replace screws securely but do
not over-tighten screws which can tear the rubber
base.

You can replace the electrode module at the
fraction of the cost of a new Testr. When the
Testr fails to calibrate or gives fl uctuating readings in calibration standards,
you need to change the electrode.
1. With dry hands, grip the ribbed Testr collar with electrode facing you.
Twist the collar counter clockwise. Save the ribbed T estr collar and
O-ring for later use.
2. Pull the old electrode module away from the Testr.
3. Align the four tabs on the new module so they match the four slots
on the Testr.
4. Gently push the module onto the slots to seat in position. Push the
smaller O-ring fully onto the new electrode module. Push the collar
over the module and thread it onto place by fi rmly twisting it clockwise.
Note the reading
once the display
stabilizes. If the
solution is above the
range of the
TDST estr, the
display will show:
Press the ON/OFF
button to turn off Testr.
Note: Testr will
automatically shut
off after 8.5
minutes of
nonuse.
HOLD FUNCTION: Press HOLD key to freeze display. Press HOLD again to release.
MAINTENANCE: To improve performance, clean the stainless steel electrodes by periodically rinsing them
in alcohol for 10-15 minutes. Replace all 4 batteries if the display becomes faint or disappears, or if the readings
are unstable or constant. If drift is detected while electrodes are continuously exposed to solution for longer than
one hour, allow electrode to fully dry off periodically.
CHANGING BATTERIES: Open the battery compartment lid. Remove old batteries and replace with fresh
ones noting polarity as shown in the battery compartment. Recalibrate Testr after battery change.
