NIST Creates Equipment Capacity Testing Accessory for Handheld Chemical Detectors

The National Institute of Science and Technology has developed an accessory device for a handheld chemical detector designed to alarm troops of potential nerve and blister agents within an environment.

The Threshold Confidence Checker was made to support the use of and evaluate the sensing capacities of Joint Chemical Agent Detector units before fielding, NIST said Wednesday.

JCADs that fail capacity tests using the TCC will be subjected to additional maintenance or returned to depot for further evaluation.

NIST noted the technology used to create simulants for the TCCs can be replicated for future configurations of sensors and handheld chemical agent detectors.

The agency said TCCs are simpler and cheaper to use than a previously determined equipment testing platform which would utilize a spectrometer to detect chemical signatures and determine vapors.
