Product Information

Description

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!

Detector

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.).

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 (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.

Selectable Alert Set Range

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

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.

Audio Indicator

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