Features & Applications:

Now with a selectable alert, the Inspector EXPDigital Radiation Alert Detector 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 which provides a 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.

Spec Summary:

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. 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

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.
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 minutes.
Timer:	Timer can set 1 minute sampling periods from 1 to 10 minutes. 10 minute sampling periods 10-60 minutes. 1 hour sampling periods from 1-24 hours.
Operating Range:	mR/hr - .001 (1µR) to 100 mR/hr CPM - 0 to 300,000 µSv/hr - .01 to 1000 CPS - 0 to 5000 Total/ Timer - 1 to 9,999,000 counts
