The Ranger EXP is a maximum performance, lightweight, rugged nuclear radiation detector to use for surveys in the field or at your facility. The Ranger EXP is designed specifically for individuals operating in tough environments.
The small, handheld Geiger counter offers excellent sensitivity to NORM and low levels of alpha, beta, gamma, and x-rays. The digital readout is displayed with a red count light and a beeper sounds with each count detected. Other features include an adjustable timer, selectable alert, and with the free Observer USB Software Family, you can download your collected data, and set alarms!
RAP-RS2 Probe – External 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.).
- 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
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.
Sulfur (35S), Strontium (90Sr/y), Cesium (137Cs), Phosphorus (32P), Carbon (14C), Iodine (131I), Cobalt (60Co), and Alpha.
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.
Meter will hold at OVER RANGE in fields as high as 100 times the maximum reading.
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.
Graphic LCD with Backlight
Red LED flashes with each radiation event.
Internally mounted beeper (can be switched off for silent operation)
