Introduction
Excessive Heat and Cold
WARNING:
Do not expose the instrument to intense sunlight for
prolonged periods.
Exposure to excessive heat or cold may result in
erroneous readings.
Introduction
Intended Use
The Multi-PID 2 measures the concentration of airborne gases and
vapors that can be ionized by a photoionization detector.
The Multi-PID 2 automatically displays and can record these concentrations.
In the TVOC mode the Multi-PID 2 does not distinguish between
individual compounds.
The reading displayed represents the total concentration of all photoionizable chemicals present in the sample. The Multi-PID 2 is factory-set to display concentration in units of ppm.
Benzene is selectively measured in GAS mode.
This measurement requires the use of the PID pre-filter tube benzene.
The pre-filter tube adsorbs all substances with the exception of benzene. Only benzene passes into the detector.

The Multi-PID 2 operates automatically. The Multi-PID 2 display
updates itself once per second. You can read concentrations directly
from the display.
The Multi-PID 2 will perform short-term exposure limit (STEL), timeweighted average (TWA) and REAL calculations when it is in INTERVAL mode. You can view any of these results in INTERVAL mode.
The Multi-PID 2 has two datalogging options, TAG and INTERVAL
mode. TAG mode allows the user to manually tag and store readings
during a walkthrough. Interval mode allows the user to datalog at selectable intervals of 3 seconds to 900 seconds.
In INTERVAL mode, the STEL, REAL and TWA are calculated. If you
select INTERVAL mode, these values are automatically recorded in
the Multi-PID 2’s memory. The Multi-PID 2 can log up to 12,000 entries.
In TAG mode operation, the Multi-PID 2 prompts you to locate a site
and then to record a background and sample readings for the site.
You can record up to 12,000 manual entries. There is no averaging of
data in TAG mode. Tags are set via the PC using the Dräger GasVision software.
19
Introduction
Recorded data can be reviewed on the display or downloaded to a
computer. Data are recorded by date and time.
The Multi-PID 2 has 5 keys for instrument operation. The keys are
used to set up and calibrate the Multi-PID 2. All information entered
with the keys and stored in the Multi-PID 2’s memory is retained when
the instrument is switched off. The clock and calendar continue to
operate and do not need to be reset when the Multi-PID 2 is turned
on.
Introduction
General Operation
The Multi-PID 2 is a microprocessor-controlled air monitor for measuring the presence of photoionizable compounds in air at parts-per-million levels. The block diagram in Figure 2 shows the main
components of the Multi-PID 2.

The microprocessor controls the components of the instrument and
interprets and records the signal generated by the photoionization
detector (PID). Recorded data and setup information entered into the
microprocessor’s memory are retained when the Multi-PID 2 is turned
off.
A pump continuously pulls the air under test through the Multi-PID 2’s
PID. The Multi-PID 2 converts the concentration of photoionizable
compounds in the sample into an electrical signal. The microprocessor subtracts any background from the signal and divides this signal
by a sensitivity obtained by calibrating with a standard gas of known
concentration. This concentration appears on the Multi-PID 2’s display and, depending on the values entered through the Multi-PID 2’s
keypad, an alarm status may be displayed and an audio signal may be
heard.
Gas Connections
00623958_01_en.eps
The Multi-PID 2 can detect thousands of different types of airborne
gases and vapors and its response depends on the characteristics as
well as the concentration of each compound.
The Multi-PID 2 does not distinguish one type of compound from
another, but displays a number indicating the total concentration
of all photoionizable compounds in the sample.
A standard of isobutylene at a known concentration may be used for
setting the sensitivity. If the Multi-PID 2 is calibrated with isobutylene,
it displays concentrations in units equivalent to ppm of isobutylene. If
isobutylene were the only photoionizable chemical in the sample,
then the Multi-PID 2 would display its concentration directly.
The Multi-PID 2 responds more or less readily to other chemicals than
it does to isobutylene. Because it has a medium sensitivity to isobutylene, this gas has been chosen as a reliable means of reporting an
average concentration of total ionizable compounds present.
Gases other than isobutylene can be used to calibrate the MultiPID 2. However, all response factors are based on an isobutylene
calibration.
21
Introduction
Photoionization Detector
The photoionization detector (PID) is shown in Figure 3. The PID measures the concentration of photoionizable chemicals in the gas
stream from the sample inlet and produces an electrical signal for the
microprocessor.
A UV lamp generates photons which ionize specific molecules in the
gas stream. The permanent air gases (argon, carbon dioxide, nitrogen, oxygen, water vapor, etc.) require a relatively high energy for ionization, and are not ionized by the UV photons. Many of the
compounds considered pollutants, including most hydrocarbons, are
ionized.
The gas stream is directed into the PID through a small port at the
center of the UV lamp window and through a series of larger ports
around the perimeter of the lamp window. This arrangement permits a
high sample flow rate and short response time.

Ionized Molecule
The ionized molecules in the detector cell are subjected to the
electric field between the electrodes. This generates a current which
is proportional to the concentration of the ionized molecules in the
detector cell. An amplifier converts the current to a voltage which is
then fed to the microprocessor.
00723958_01_en.eps
The UV lamp is operated by a high voltage lamp driver circuit which
injects its energy through plates in the lamp holder.
The lamp driver power supply is controlled by the microprocessor
based on a feedback signal from a light sensor on the driver circuit
board.

Calibration
For normal operation these items are required:
1. Calibration Gas Regulator (Part No. 68 10 688).
2. Calibration gas containing 100 ppm isobutylene (Part No.
68 10 687). Other concentrations of the calibration gas may be required. This will depend on your application.
3. Zero air (clean dry air without any organic impurities)
There are several alternatives for clean or zero air calibration: you
can use a bottle of clean air (certified as having not more than
0.1 ppm total hydrocarbons) connected directly to the instrument;
the clean air can be transferred to a Tedlar bag which can then be
connected to the instrument; clean, ambient air without detectable
contamination; or, ambient air run first through the charcoal filter
(Part No. CH 24 101).
4. If compound threshold limit values (TLVs) are exceeded, you
should use a gas bag for sampling and calibration.

pack, the Multi-PID 2 or the adapter itself.
To charge the battery pack:
1. Plug the AC adapter into the jack located on the bottom of the
Multi-PID 2.
2. Plug the AC adapter into an AC outlet. If you are using the European AC adapter, ensure the correct plug is installed on the line
cord. If it is not correct for the wall outlet in your area, then it must
be replaced.
3. The Charge LED on the Multi-PID 2 indicates the charge state.
Red indicates the battery is being charged. Green indicates the
battery is fully charged and ready for use.
It is normal for a fully charged battery to indicate it is charging (red
light) when first plugged in. The Charge LED will turn green within
a few minutes to indicate the battery is fully charged.
4. When the battery pack is fully charged, remove the AC adapter
first from the wall outlet and then from the Multi-PID 2.

Using the Multi-PID 2
Charging a fully discharged battery pack will take approximately
4 hours.
Optionally you can use the off line charger (Part No. 64 05 404) to
charge the battery pack when not installed in the Multi-PID 2.
If you are charging the battery pack in the instrument you can use all
the features of the Multi-PID 2 while the battery pack is being charged.
Leaving the AC adapter connected to the Multi-PID 2 will not harm
the battery or the AC adapter in any way. If the Multi-PID 2 is to be left
unused for an extended period of time, leave it connected to the AC
adapter so that the battery will be fully charged and ready for operation.
On average a fully charged battery pack will provide 8 hours of continuous operation. Battery life is shorter if the instrument is turned off
and then on again repeatedly, or if the backlighting is turned on.

Display
The Multi-PID 2 has a graphic display for reporting detected concentration and to guide you through configuration options. All functions
of the Multi-PID 2 will be reported on the display.
Graphic Display
The Multi-PID 2 uses an 8 line graphic display. The display will always
be used for reporting detected concentration. In order to accommodate the range of concentrations the Multi-PID 2 can detect, the
meter reading will be reported using one of two resolutions. A resolution of 0.1 ppm will be used for concentrations below 100 ppm, and a
resolution of 1 ppm will be used for concentrations above 100 ppm .

The display reports instantaneous concentration at all times when the
pump is on. In Interval mode, the display will report instantaneous
concentrations as well as REAL, STEL or TWA.
The Multi-PID 2 is designed for ease of use with a logically organized
internal menu structure/user interface.
The Multi-PID 2 User Menu is shown in Figures 6 and 7.
The Multi-PID 2 has three soft keys under the graphic LCD display,
which always show the available functions of the soft keys in any
screen.
