Radiation detection in a compact hand-held unit
The Inspector is a microprocessor controlled radiation measuring instrument which offers excellent sensitivity to low levels of alpha, beta, gamma and x-rays. The digital readout is displayed with a red count light and audible beep, providing instant indications of the radiation level. Other benefits include an adjustable timer and external calibration controls.
• Monitors alpha, beta, gamma, and x-ray radiation
• Range: 0-300, 000 cpm
• 4-digit LCD readout
• Red LED count light
• Audible beeper ( can be switched off)
• External calibration controls
• Adjustable timer with: 1-minute sampling periods from 1 to 10 minutes 10-minute sampling periods from 10 to 60 minutes 1-hour sampling periods from 1 to 24 hours
• Operates 200 hours on 9V battery
• User selectable display for mR/ hr or sieverts

Specifications :
• Detector: Halogen-quenched uncompensated GM tube with thin mica window, 1.4-2.0 mg/ cm2 area density.
• Window: 1.75" ( 45 mm) effective diameter
• Display: Four-digit liquid crystal display with indicators
• Averaging Periods: Display will update every three seconds; at low background levels, the update is the moving average for the past 30-second time period; time period for moving average decreases as radiation level increases
• Gamma Sensitivity: 3500 cpm/ mR/ hr ( referenced to Cs-137) ; smallest detectable level for I-125 is .02 ¼ Ci at contact
• Operating Range: mR/ hr - .001 ( 1¼ R) to 100 mR/ hr, ¼ Sv/ hr - .01 to 1000, CPM - 0 to 300, 000, CPS - 0 to 5000 Total/ Timer - 1 to 9, 999, 000 counts
• Accuracy ( Referenced to Cs-137) : mR/ hr ± 15% from 0 to 30 mR/ hr, ± 20% from 30 to 50 mR/ hr CPM ± 15% from 0 to 100, 000 cpm, ± 20% from 100, 000 to 300, 000 cpm
• Timer: Can set 1-minute sampling periods from 1 to 10 minutes, 10-minute sampling periods from 10 to 60 minutes, 1-hour sampling periods from 1 to 24 hours
• 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 for counting to computer or data logger; ( Submini jack input allows for electronic calibration)
• Utility Menu: Options accessed by holding down " + " button while turning instrument on: 3-second ( fast response) , switch from mR/ hr and CPM to ¼ Sv/ hr and CPS, reset cal factor to 100, adjust probe settings, adjust the CAL factor, reset all setting to original factory setting ( default)
• Anti-Saturation: Meter will hold at full scale in fields as high as 100 times the maximum reading
• Power Requirements: ( 1) 9-volt alkaline battery
• Temperature Range: 14° F to 122° F ( -10° C to + 50° C)
• Battery Life: Typically 200 hours at normal background radiation levels
• Dimensions: 5.9" h x 3.3" w x 1.2" d ( 15 x 8 x 3 cm)
• Weight: 10.6 oz ( 300 grams) without battery
