The Inspector is a small, handheld, microprocessor-based instrument which offers excellent sensitivity to low levels of alpha, beta, gamma, and x-rays. The digital readout is displayed with a red count light and a beeper sounds with each count detected. Other features include an adjustable timer, external calibration controls and adjustable alert.

Internal Halogen-quenched, uncompensated GM tube with thin mica window, 1.4-2.0 mg/cm2 areal density. Effective diameter of window is 45 mm (1.75 in.). Radiation symbol on front label marks the center of the detector.

Averaging Periods
Display will update every 3 seconds. At low background levels, the update is the moving average for the past 30-second time period. The timed period for the moving average decreases as the radiation level increases.

Operating Range
mR/hr - .001 (1μR) to 100 CPM - 0 to 350,000 μSv/hr - .01 to 1000 CPS - 0 to 5000 Total/Timer - 1 to 9,999,000 counts

Accuracy (Cs137)
mR/hr ±10% typical (NIST), ±15% max - 0 to 100 μSv/hr ±10% typical (NIST), ±15% max - 01 - 1000 CPM ±10% typical (NIST), ±15% max - 0 to 350,000

Energy Sensitivity
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 end window. 3340 CPM/mR/hr (Cs137). Smallest detectable level for I125 is .02 μCi at contact.
