Inspector Alert Handheld Surface Contamination Meter

The Inspector Alert measures alpha, beta, gamma and x-radiation using a 2-inch “pancake” GM detector with high sensitivity to common beta and alpha sources.The easy-to-read digital display shows readings in your choice of mR/hr, CPM, CPS, or µSv/hr. The Total/Timer feature allows timed readings from one minute to 24 hours for precise measurement of low level contamination. An audible alert sounds when the radiation reaches a user-adjustable level.Quickly alerts first responders to the presence of harmful levels of nuclear radiationImproves safety in the laboratory and in the fieldAutomatically compensates for GM tube dead timeWill not jam in high radiation fieldsMeets CE certification requirements for EuropeSpecifications:Detector:Halogen-quenched Geiger-Mueller tube.

Averaging Periods:Display updates every 3 seconds, showing the average for the past 30-second time period at normal levels. The averaging period decreases as the radiation level increases. User can select a fast 3-second averaging period.Timer:Can set 1-10 minute sampling periods in one-minute increments, 10-50 minute sampling periods in 10-minute increments, and 1-24 hour sampling periods in 1-hour incrementsAlert:Beeper sounds the alertUser-adjustable alert level is set using three buttonsAccuracy:± 15% up to 50 mR/hr; ± 20% up to 100 mR/hrAnti-Saturation:Readout holds at full scale in fields up to 100 times the maximum readingTemperature Range:-20º to +50º C , -4º to +122º FPower:One 9-volt alkaline battery; battery life is average 2160 hours at normal background, average 625 hours at 1 mR/hr with beeper offSize:150 x 80 x 30 mm (5.9″ x 3.2″ x 1.2″)Weight:323 grams (11.4 oz) including batteryI/O Ports:Dual miniature jack for CMOS or TTL devices, sending counts to computer or data logger.
