Halogen-quenched GM tube with thin mica end window. Mica window density 1.5-2.0 mg/cm2. Effective diameter of window is 45 mm (1.77 in.). Side wall is .012 inch thick.
µR/hr – 1 to 50,000
CPM – 0.0 to 175,000
nSv/hr – 1 to 500,000
CPS – 0.0 to 2500
Typically ±15% from factory. , ±10% (NIST).
Readout will OVERRANGE in radiation fields as high as 100 times the maximum reading.
Detects Alpha down to 2 MeV. Detects Beta down to .16 MeV; typical detection efficiency at 1 MeV is approx. 25%. Detects Gamma down to 10 KeV through the detector window. 3600 CPM/mR/hr (137Cs). Smallest detectable level for 125I is .02 µCi at contact.
Backlit liquid crystal display with mode indicators.
Pulsating beeper sounds the alert. Adjustable alert levels are used for µR/hr / CPM, and nSv/hr / CPS.
Red LED flashes with each count.
Sounds with each count (can be switched off for silent operation)
Carrying Case, Lanyard, Batteries, and Protective Boot. Protective boot fits most industry standard dose rate and compensation filters.
Two (2) AA alkaline batteries (included). Battery life is approx. 1000 hours at normal background radiation levels.
