SE International Ranger EXP Radiation Detector (CPM: 0 ~ 350,000)

Detector: RAP-RS2 Probe – External Probe 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.).

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

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 (137Cs). Smallest detectable level for 125I is .02 µCi at contact.

Built-In Efficiencies: Sulfur (35S), Strontium (90Sr/y), Cesium (137Cs), Phosphorus (32P), Carbon (14C), Iodine (131I), Cobalt (60Co), and Alpha

Accuracy

Reference to Cs137

Typically ±15% from factory, ±10% with NIST Source Calibration 

Selectable Alert Settings: mR/hr .001 – 100 and CPM 1 – 350,000. 70db @ 1m. Pulsating beeper sounds the alert. Adjustable alert levels are used for mR/hr / CPM, and µSv/hr / CPS. 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: This Radiation detector 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

Outputs: USB for use with Free Observer USB Software for PCsBluetooth Option: Wirelessly connects the instrument with an Android mobile device for use with Free Observer BLE App

Count Light: Red LED flashes with each radiation event.

Audio Indicator: Internally mounted beeper (can be switched off for silent operation)

Power Requirements: USB Power or Two (2) AA alkaline batteries (included). Approx. 800 hrs @ background.

Temperature Range: -10° to +50°C (14° to 122°F)

Humidity: 10% to 70% Non-Condensing.
