What is the HAZMATCADTM?
The HAZMATCAD™ is a next generation handheld trace chemical agent detector for Nerve (G) and Blister (H) agents as well as Hydrogen Cyanide (AC) or Phosgene (CG). The HAZMATCAD™ is designed to detect for these warfare agent gases with minimal interference from other chemicals which are often present in the battlefield or urban environment.
The HAZMATCAD™ Plus expands the
performance of HAZMATCAD™ by adding the ability to detect selected TICs (Toxic Industrial Chemicals). These chemicals are detected and reported by class identification (hydride and halogen gases).
What is the HAZMATCAD™ Plus?
HAZMATCAD™
SAW (nerve and blister)
One electrochemical cell (blood or choke)
HAZMATCAD™ Plus
SAW (nerve and blister)
Four electrochemical cells (blood, choke, halogen and hydride gases)
HAZMATCAD™ Configurations
Fast Response Time – IMS – Typically (5 to 30 sec)Direct readout of total contamination
No sample pre-collection or clean up
Increased risk of false positives
HAZMATCAD™ Analysis Time – SAW (20 to 120 sec)
Fast Mode (20 sec) or High Sensitivity Mode (120 sec)
Sample collection on absorbant media
Sample control
Reduced risk of false positives

Check Source Verification
Chemical Simulant for “G” Agent−Dimethyl Methlyphosphonate (DMMP)
Verify Check Source Expiration Date−6 months from date on tube−MSDS - Appendix A in Operation Manual
A Successful Test indicates the HAZMATCADTM is fully operational for Nerve and Blister Agent Detection
No need to test separately for Blister
How to use Simulant Check Source
Power Up HAZMATCADTM
Allow HAZMATCADTM to report “ALL CLEAR”
Prepare Check Source - remove vinyl end caps
Position Sample Inlet to “OPEN” position
Listen for Pump Operation−When pump pauses, wait 10 seconds−Hold Simulant Check Source to Sample Inlet for
3 seconds then remove
“G” Alarm should be indicated on next analysis
Allow HAZMATCADTM to return to “ALL CLEAR”
HAZMATCADTM Li-Ion Battery
2 SONY NP-F550 Rechargeable Lithium Ion Batteries
Can operate on one battery
8 to 12 hours of operation (dependent on Mode)• Fast Mode = 8 hours• High Sensitivity Mode = 12 hours
Can remove batteries while operating (HOT SWAP)
NP-F550 batteries require periodic charging
Typical recharge time is approximately 1 hour
Battery charger will indicate charge level
HAZMATCADTM Decontamination
Turn HAZMATCAD OFF
Place the three position sample port in the CLOSED position
Wipe down completely with moist, soapy cloth
Shake HAZMATCAD briskly to remove residual liquid
Place three position sample port in OPEN position and invert HAZMATCAD for two minutes
Wipe dry with clean towel, paper towel or clean rag
Place the HAZMATCAD in a sealed bag for one hour
Sample the headspace of the bag using another HAZMATCAD, M256 kit or other appropriate device
If residual contamination is detected, repeat steps 1 thru 8
HAZMATCADTM Check forInternal Contamination
Place an operating HAZMATCAD in a large plastic bag and seal it
Let the HAZMATCAD run for 60 minutes
Sample the headspace of the bag with another HAZMATCAD, M256 kit or other appropriate device for trace contamination
If contamination is detected, run the HAZMATCAD in clean air for several hours and repeat steps 1 thru 3
If HAZMATCAD still shows traces of contamination, contact Microsensor Systems, Inc. or the appropriate government agency
Data Log / Communication
External Modem Software Program (ProComm) ► Null Modem Cable ► 9600 Baud N-8-1 Serial Port Communication
