The Model 12S is a high sensitivity gamma microR (μR) meter employing an internally housed 2.5 x 2.5 cm (1 x 1 in.) NaI detector. The cast aluminum instrument housing with its separate battery compartment and accompanying metal handle offer an industrial robustness and quality that promote long lasting protection and instrument life. The front-panel controls include a rotary switch for selecting the four-decade range and instrument shut-off and battery test, an audio on/off switch, a fast/slow response switch, and a count reset push button. The Model 12S is a complete turn-key system and includes two "D" cell batteries.
