The Inspector EXP was designed to meet the requirements of emergency response personnel. It has the same valuable features, small size, and quality of the Inspector. However, instead of the built-in detector, it has the added versatility of an external probe. The carrying case has a clear window panel providing full view of the readout, count light, access to the switches, and a convenient belt loop for carrying the instrument. A small pocket is provided for a check source. The protective probe cover on the uniquely designed carrying case folds easily out of the way to allow one-handed operation if desired.

Specifications

Detector
RAP-RS1 Probe - External 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
Alert Set Range
mR/hr .001 - 50 and CPM 1 - 160,000.
70db @ 1m.
Count Light
Red LED flashes with each radiation event.
Audio Indicator
Internally mounted beeper (can be switched off for silent operation)
Outputs
Dual miniature jack drives CMOS or TTL devices: count to computer or datalogger. Submini jack input allows for electronic calibration

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.
