ELECTRICAL HAZARD
The CLPX may only be serviced by trained service
personnel. Contact the manufacturer for more information
.
Be sure to read this manual in its entirety before installing and operating the CLPX. Contact
the manufacturer with any questions regarding the installation or use of the CLPX.
IMPORTANT : Read Appendix G before handling ChemLogic Cassettes.
Chapter 1 - Overview
1.1 Introduction
The DOD Technologies CLPX portable gas monitor is an analytical instrument designed to measure
low concentrations of a specific toxic gas or a specific range of related toxic gases or vapors. This
equipment is intended to be used as part of a defined air quality management program.
The CLPX uses DOD Technologies ChemLogic colorimetric technology for fast and accurate gas
detection. The CLPX provides a fast response to a wide range of gases. It was designed for maximum
uptime, so routine maintenance and service can be performed quickly and easily.
Use only ChemLogic cassettes labeled for use with CLPX.
1.2 Sampling and Monitoring
The system draws sample flow through the inlet on the front of the unit and through the ChemLogic
tape.
1.3 Flow
An optional kit allows a short exhaust tube to be used with the CLPX unit. Contact DOD for more
information.

1.4 Electrical
The unit is powered with a 6Volt rechargeable Lead Acid Battery. Use only the included charger to charge
the unit.
1.5 Theory of operation
During the analysis cycle the pump draws a measured sample of air through a chemically
impregnated “ChemLogic” paper tape. The ChemLogic tape reacts to the presence of the specific
contaminants by darkening from its original paper color. Light is bounced off the dark stain and
sensitive optics repeatedly measure the degree of change from the original color. The CLPX uses an
advanced optical detection system to measure the light level reflected from the ChemLogic tape. The
instrument calculates the change as the level of gas present in the sample. Extremely small
concentrations can be detected with this method. The instrument stores the gas level readings on the
MicroSD card for transfer to a computer for further analysis in standard comma separated values
(CSV) format.
If the calculated value indicates that the concentration has exceeded either the Low or High
ALARM set points, the instrument will sound an ALARM and flash the concentration level in the
backlit display. The CLPX automatically calculates the Short Term Exposure Limit (STEL) for the
selected gas and stores the readings in the internal data storage memory and to a MicroSD flash
memory card (if installed).
The ChemLogic paper tape is contained within a removable tape cassette. The CLPX monitor
automatically advances the roll to position a fresh segment of tape for gas sampling. Each cassette
is sealed into a protective package, and marked with expiration date and serial number. Cassette life
will vary depending the operational conditions and concentration levels of the gas being monitored.

6.2 Routine Maintenance
Reliable operation of the CLPX monitor requires that the unit be maintained in good working order
and that the sample input path and tape transport area are clean. Regularly inspect the CLPX
monitor for proper operation and damage. Establish a schedule for cleaning the CLPX monitor
based or usage and the nature of the sampling environment and clean as needed according to the
cleaning instructions below. If you have any questions or concerns, contact DOD Technologies.
6.2.a Inspection of the CLPX
1. Inspect the CLPX monitor for damage such as cracks to the housings or loose or missing
components.
2. Check the tape door release and lock for proper operation. Check the tape door for damage.
3. Check the sample input path for damage or for missing components.
4. The inlet tube must be properly seated in the optics block and flush with the end of the cover
tube.
5. Start the unit and check for any performance issues such as excessive or unusual noise, erratic
operation, or problems with the display. If any damage is found, remove the unit from service
and tag for repair by authorized personnel.
6.2.b Cleaning the CLPX
Cleaning of the CLPX portable gas monitor is essential to maintain reliable and accurate
measurements. Problems with calibration may be an indication of the need for cleaning. Dust and
contaminants can build up and interfere with the sensitive optics. Most routine cleaning of the CLPX
monitor involves removal of tape dust build up and cleaning of the sample input path. Additional
cleaning may be required in dusty environments or in some atmospheres, such as those where MDI is
being measured, which may contain wet or sticky aerosols that can build up in the sample input path.
Establish a cleaning schedule that is suitable for the conditions where the CLPX monitor will be used.
Wear powder-free surgical gloves (or equivalent) when cleaning the interior surfaces and
mechanism to avoid contact with the paper tape dust and other contaminants and when handling
pieces of the paper tape in the course of these instructions.
Cleaning the CLPX monitor may require the use of pressurized air. For some cleaning, a rubber

bulb blower will provide a good puff of air to remove dust. Avoid the use of a photographic blower
brush which may snag and leave brush hair in the mechanism. If compressed air is used, use only
clean, dry air at a maximum pressure of 30 psi. Never use shop air which may contain oil or other
contaminants. Canned compressed air for photographic or electronic cleaning is recommended
when used in accordance with the product If a spray solvent cleaner is required, use only a residue
free cleaner such as an aerosol contact and circuit board cleaner. Follow the manufacturer’s
instructions for proper use of the cleaner.
WARNING : COMPRESSED AIR IS HAZARDOUS. CARELESS HANDLING OF
COMPRESSED AIR MAY RESULT IN SERIOUS INJURY OR DEATH
6.2.c Cleaning the Exterior
Clean the outside of the CLPX monitor with a damp cloth. Keep the tape door closed and avoid
excessive water. To remove oily or sticky deposits, use a mild detergent solution on the cloth.
6.2.d Cleaning the Interior
For routine cleaning, carefully wipe the inside of the cassette chamber but avoid contact with the tape
gate, the sample input path, and the optic block. Cleaning the tape gate, the sample input path, and the
optic block are described below.
6.2.e Cleaning the Gate
When a sample is being taken, the paper tape is held in place by the tape gate. When the sample is
complete, the gate opens and the tape advances a new segment of tape into position for the next test.
Paper dust from the tape may accumulate in the tape gate area. To clean the tape gate area, use a rubber
bulb blower or clean pressurized air

*** IMPORTANT The expiration date of all ChemLogic tapes is printed on the label on
each cassette. However once the package is opened the maxium days the cassette can be used
without proper storage is indicated in the table. The effective expiration date is the sooner of
the expiration date on the label or the appropriate number of days from the date opened.
Example: A cassette part # 1-600-070 has the expiration date of 11/31/2012 printed on the
label. It is opened on 05/01/2012 and kept in the CLPX. The actual expiration date would be
6/29/2012 (60 days after opening).
If the cassette is returned to storage in the original packaging (including black bag) after each
use the cassette can be used up to the original expiration date printed on the label.
When the ChemLogic Cassette package is first opened the date
should be recorded on the cassette for reference.

Appendix G – ChemLogic Cassettes
DOD ChemLogic cassettes are designed for use in colorimetric based gas monitoring
systems. Since this is a particular end-use function and does not release or result in
exposure to hazardous chemicals under normal use Material Safety Data Sheets (MSDS)
are not required.
ChemLogic cassettes are non-toxic and require no special precautions for protection.
However contact with skin may cause the cassette to react, change color, and no longer
be useful in your gas monitoring system. We therefore recommend that rubber gloves be
worn at all times while handling including removal and installation. Always wash hands
as a precaution after handling DOD Chemlogic cassettes.
