Now with USB and the included Observer USB Software, you can download your data from the internal memory, set computer alarms, and calibrate your instrument! The Inspector USB Handheld Digital Radiation Alert® Detector is a small, microprocessor based survey meter which offers excellent sensitivity to low levels of alpha, beta, gamma, x-rays, and built in effciencies for common isotopes to calculate activity in Bequerels and DPM.
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 (1.77 in.). Radiation symbol on front label marks the center of the detector.
Averaging Periods
Display will update every 3 seconds. At low back-ground 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 effciency 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 I 125 is .02 µCi at contact.
Display
Backlit 4 digit liquid crystal display with indicators.
Display updates every 3 seconds.
Alert Set Range
mR/hr .001 - 50 and CPM 1 - 160,000. 70db @ 1m.
Count Light
Red LED fashes with each radiation event.
