S.E. International Inspector EXP + Digital Radiation Detector with External GM Probe

The Inspector EXP was designed for the requirements of emergency response personnel. It has the same valuable features, small size, and quality of the Inspector, but 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, and access to the switches. Convenient hand straps and a belt loop are provided for carrying the instrument. A small pocket is provided for a check source. The unique design of attaching the probe to the carrying case allows one-handed operation if desired. The protective probe cover folds easily out of the way during one-handed operation.

Radiation symbol on front label marks the center of the detector.
Inspector⁺ EXP (External probe)
RAP-RS1 Probe:
Same GM tube as Inspector⁺. Anodized aluminum housing with coated, black foam grip.
500-volt power supply is in the probe head.
Size- Approx. length: 22.2 cm (8.75 in.) Diameter: 7 cm (2.75 in.)
Connector - Amphenol tuchel connectors

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
Operating Range
mR/hr - .001 (1µR) to 100 mR/hr
µSv/hr - .01 to 1000
CPM - 0 to 350,000
CPS - 0 to 5000
Total/ Timer - 1 to 9,999,000 counts
Accuracy
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
(Referenced to Cs-137)
Alert Set Range
mR/hr .001 - 50 and CPM 1 - 160,000
Gamma Sensitivity
3500 CPM/mR/hr referenced to Cs-137. Smallest detectable level for I-125 is .02 µCi at contact.
 

Timer
Can set 1 minute sampling periods from 1 to 10 min
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
Anti-Saturation
Meter will hold at full scale in fields as high as 100 times the maximum reading.
Power Requirements
One 9-volt alkaline battery. Battery life is 2160 hours at normal background.
Temperature Range
-10ºC to 50ºC (14ºF to 122ºF)
Weight
Inspector: 880.2 grams (28.0 oz.) without battery.
Size
150 x 80 x 30 mm (5.9 x 3.3 x 1.2 in.).
