STS - Model AP3 - Large Area Contamination Probe
The STS AP3 is a real AP3 probe , but with a STS gas detection head rather than a real detector. STS electronics installed within the host instrument power the gas detection system and the signal generated is displayed on the host instrument as counts. The Probe detects the presence of the STS LS1 liquid simulant spray placed on surfaces and clothing.
The STS AP3 is not designed to be intrinsically safe and therefore should not be used in hazardous environments. The units are not waterproof and contain delicate and sensitive electronics which may be caused to fail if exposed to moisture. Units should be stored in a clean and dry environment.
Instrument response may be affected by environmental conditions such as excessive heat and humidity and by air flow, strong air conditioning units and outside exercises may need to be considered to ensure the simulant is identifiable by a trainee.
