the Geiger-Müller principle
Stainless steel housing
Measuring length 38.1 mm, measuring diameter 9.1 mm
Mica window 1.5 to 2 mg/cm2

Zero rate <10 pulses per minute with sreening by 3mm AI and
50mm Pb Operating temperature -20 bis +60°C, operating voltage
approx. 450 V Calibrated scale 0.01 μSv/h up to 5000.00 μSv/h
