The Model 192 is a high-sensitivity gamma μR ratemeter employing an internally housed 5.1 x 2.5 cm (2 x 1 in.) NaI(Tl) detector. This instrument supports two types of alarms: a user adjustable fixed point alarm and a deviation alarm that activates at levels above a floating background. An alarm light is mounted to the front panel and is accompanied by an audio signal.

The front-panel controls include a rotary switch for selecting one of four ranges, instrument shut-off and battery test, an audio on/off switch, a fast/slow response switch, and a reset button. The cast aluminum instrument housing with a separate battery compartment and accompanying metal handle offer an industrial robustness and quality that promote long-lasting protection and instrument life. The Model 192 is a complete turnkey system and includes two "D" cell batteries.
