Radiation Alert™ Ranger Radiation Detector

The Ranger offers maximum performance in a lightweight, rugged solution for surveying at the facility or in the field. The Ranger has been designed for industrial environments, but it still has all of the features you’ve come to love in the lab. The Ranger is a small, handheld, digital radiation survery meter which offers excellent sensitivity to low levels of alpha, beta, gamma, and x-rays. It has built in efficiencies for common isotopes to calculate activity in Bq and DPM. It has a backlit digital display, a red count light, and a beeper that sounds with each count detected. Other features
include selectable alert levels, an adjustable timer, and an optional wipe test plate for swipes. Internal memory and the free Observer USB Software allow you to set computer alarms, select preferences and download your collected data from the internal memory for easy reporting and calibrate your instrument.

Specifications
Detector: Internal Halogen-quenched, uncompensated GM tube with thin mica window, 1.4-2.0 mg/cm2 areal density. Effective diameter of window is 45 mm (1.77 in.).
Operating Range: mR/hr - .001 (1µR) to 100, CPM - 0 to 350,000, µSv/hr - .01 to 1000, CPS - 0 to 5000
Total Counts - 1 to 9,999,000 counts
Accuracy: (Referenced to Cs137) Typically –15% from factory, –10%with NIST Source Calibration
Energy Sensitivity: Detects Alpha down to 2 MeV., • Detects Beta down to .16 MeV; typical detection efficiency at 1
MeV is approx. 25%., • Detects Gamma down to 10 KeV through the detector window.
3340 CPM/mR/hr (Cs137) Smallest detectable level for I125 is .02 µCi at contact.
Built-In Efficiencies: Sulfur (35S), Strontium (90Sr/y), Cesium, (Cs137), Phosphorus (32P), Carbon (14C), Iodine (131I), Cobalt, (60Co), and Alpha

Selectable Alert Set Range: mR/hr .001 - 100 and CPM 1 - 350,000. Pulsating beeper sounds the alert. Adjustable alert levels are used for mR/hr / CPM, and µSv/hr / CPS. 70db @ 1m. Alarm will sound when in Timer Mode when set alarm threshold is reached.
Anti-Saturation: Meter will hold at OVER RANGE in fields as high as 100 times the maximum reading
Averaging Periods: Display updates every 3 seconds. At low background levels, the update is the average for the past 30-second time period. The timed period for the average decreases as the radiation level increases.
Display: Graphic LCD with Backlight
Count Light: Red LED flashes with each radiation event
Alarm Indicator: Internal beeper. 70db @ 1m. (can be switched off for silent operation)
Outputs: USB for use with Observer USB Software for PCs, Bluetooth for use with the Observer BLE app for Android OS
Temperature Range: 14° to 122°F ( -10° to 50°C)
Size: 5.5” X 2.7” X 1.3” (14.0 X 6.8 X 3.3 cm)
Weight: 10.3 oz (0.64 lbs.)
