Inspector EXP Handheld Digital Radiation Alert Detector Model:W849

Now with a selectable alert, 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. A convenient belt loop is 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.
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 back of probe 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
