The palmRAD 907 nuclear radiation meter provides multiple monitoring and surveying options in an easy-to-use handheld device. It measures alpha, beta, gamma and x-ray radiation which can be displayed in rates and total counts. The user can switch between mR/hr, Svi cpm and total counts. There is a digital display of the selected mode and three other types of indicators - a LED indicator, an audio alarm and an audio chirp. The LED flashes with each count. The palmRAD 907 has a user adjustable alarm threshold. When the selected level has been exceeded the powerful audio alarm will sound. The audio chirp, when enabled, emits a single chirp with each count detected. Put low cost, reliable and proven nuclear radiation detection in the palm of your hand.

Detector: Halogen-quenched Geiger-Mueller tube. Effective diameter 1.75" (45 mm). Mica window density 1.5-2.0 mg/cm
Display: 4-digit liquid crystal display with mode indicators
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 fast 3-second averaging period.
Operating Range: mR/hr: .001 to 100.0; CPM: 0 to 300,000; Total: 1 to 9,999,000 counts; mSv/hr: .01 to 1,000; CPS: 0 to 5,000
Efficiency: Sr-90 (546KeV, 2.3MeV max): approx. 75%; C-14 (156KeV max): approx. 11%; Bi-210 (1.2 MeV max): approx. 64%; Am-241 (5.5 MeV ): approx. 36%
Sensitivity: 3500 CPM/mR/hr referenced to Cs-137
Accuracy: ± 15%
Timer: Can set 1-10 minute sampling periods in 1-minute increments, 10-50 minute sampling periods in 10-minute increments, and 1-24 hour sampling periods in 1-hour increments
Count Light: Red LED flashes with each radiation event
Audio: Beeper beeps with each radiation event; can be muted
Outputs: Dual miniature jack drives CMOS or TTL devices, sending counts to computer or data logger. Submini jack allows for electronic calibration.
Anti-Saturation: Readout holds at full scale in fields up to 100 times the maximum reading
Temperature Range: -10° to +50° C , 14° to 122° F
Power: One 9-volt alkaline battery; battery life is minimum 200 hours at normal background, minimum 24 hours at 1 mR/hr
Size: 150 x 80 x 30 mm (5.9"; x 3.2"; x 1.2")
