IMPORTANT
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.
Chapter1 -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.
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.
IMPORTANT
:
Use only ChemLogic cassettes labeled for use with CLPX.
IMPORTANT : Read Appendix G before handling ChemLogic Cassettes

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.

2.1.1 Cassette Access Door
The cassette access door is used to load/unload ChemLogic cassettes into the CLPX. To open the door turn
the door latch release knob counter clockwise until it stops which will release the latch from the door. Pull
the door down to insert/remove the cassette. When complete close the door and turn the knob clockwise to
latch the door.
Figure 2.2
2.1.2 Keypad & Display
The CLPX uses a two color LCD display with a 5 button keypad See chapter 5 for a complete description
on the use of the keypad and display.
IMPORTANT: The doo should emain closed and latched except when changing the
ChemLogic cassette.

2.1.3 ChemLogic tape and Take-up Reel
ChemLogic paper tapes are accessed by opening the door as described in section 2.1.1.
2.1.4 Gas Inlet/Exhaust
Sample is pulled through the inlet on the front of the unit, through the paper tape and further scrubbed via a
charcoal filter inside the unit.
2.1.5 Power
Power the unit on by pressing the enter button. See chapter 5 for complete operation.
2.2 Micro Secure Digital (SD) card
The CLPX uses a MicroSD card to store historical information including concentration logging, event
history, STEL and configuration information. SD cards may be purchased through DOD Technologies – see
Appendix A.
Care should be taken when inserting and removing the MicroSD card. Do not insert or remove the MicroSD
card while the machine is in operation. Power down the machine first then insert or remove the MicroSD
card to assure no data is lost or the card is corrupted.
Standard MicroSD cards may be used with either FAT16 or FAT32 format. See Appendix F for information
on the data stored to the MicroSD card.

Chapter3–What’sincluded
3.1 Unpacking the CLPX case.
The CLPX comes in a convenient durable hard shell storage case with a handle for easy transport. Included
in the case are:
•A 0-500cc flow meter with a short tube for use when adjusting the pump and.verifying proper flow
at any time during sampling.
•A battery charger with a charging indication light
•A shoulder strap with two rings to attach to the CLPX
The case can also hold up to two (2) ChemLogic cassettes. Be sure to read the DOD Technologies
recommended storage guides for the specific types of cassettes being used.
Use care when handling the CLPX portable gas monitor. Although the CLPX monitor is ruggedly
built it is a sensitive instrument. Do not drop the monitor or expose it to excessive moisture or heat
that could cause damage to the mechanism or electronics. Establish a schedule for cleaning and
regularly inspect the unit for damage. If any damage is found or the monitor does not operate as
described in these instructions, remove the unit from service and tag for repair by authorized
personnel.
