S.E. Digilert 200 Geiger Counter Digital Handheld Nuclear Radiation Monitor

Formerly the Digilert 200, The Monitor 200 measures alpha, beta, gamma, and x-rays. Its digital display shows readings in your choice of CPM, CPS, µSv/hr, mR/hr, or in accumulated counts. It has a digital display, a red count light, and a beeper that sounds with each count detected. Other features include an adjustable timer, and selectable alert. With the free Observer USB Software Family, you can set computer alarms, calibrate your instrument, and download your collected data from the internal memory for easy reporting!

Features and Specifications Detector: Halogen-quenched GM tube with thin mica end window Mica Window Density: 1.5-2.0 mg/cm2. Effective window diameter is .360 inch. Side wall is .012 inch thick Display: Backlit 4-digit liquid crystal display with mode indicators. Display updates every 3 seconds Count Light: Red LED flashes with each count Audio Indicator: Sounds with each count Alert: Pulsating beeper sounds the alert. Adjustable alert levels are used for mR/hr / CPM, and µSv/hr / CPS.
