Abstract
Abstract A chemical agent detector having a pair of vapor/aerosol chemical agent dctor cells mounted with a lithium battery in a detection cell module. A liquid agent detector having a hinged plate is attached to an electronic system which includes a signal processor that energizes a plurality of warning LED's and a horn in response to energization of selected agent detectors. An air pump is mounted on the housing for the electronics to force air across the detection cells. The detection cell module is connected to the housing for the electronics. A battery compartment is connected to the detection cell module and includes means for permitting an external power source to be connected thereto.
