Specification :

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.

Specifications:

• Detector
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.
• Display
4 digit liquid crystal display with indicators.
• 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
• 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 µ Ci at contact.
• Operating Range
mR/ hr - .001 ( 1µ R) to 100
µ Sv/ hr - .01 to 1000
