  • Rugged
  • Splashproof Protection for Outdoor Use
  • 2000 Hour Battery life
  • Meter Light

The Model 19 is a highly sensitive gamma microR meter employing an internally housed, 2.5 x 2.5 cm (1.0 x 1.0 in.) NaI detector. The measuring range is 0 to 5000 µR/hr. (For µSv/h, use Model 19 Series 8, P/N: 48-2582.) 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 front-panel controls include a rotary switch for selecting the five-decade range and instrument shut-off, an audio on/off switch, a fast/slow response switch, and pushbuttons for activating the meter lamp, high-voltage display, battery test, and count reset. The Model 19 is a complete turn-key system and includes two "D" cell batteries.

Note: While the detector used in this instrument is sensitive and is often used for detection of near-background levels of radiation, its nonlinear energy response means that dose and exposure measurements may be over/underreported.
