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.
