Radiation Alert® Ranger EXP

Radiation Alert® Ranger EXP

The Ranger EXP is a high performance, durable, lightweight radiation detector for field use or in your facility. This Radiation detector 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!

SPECIFICATIONS

Detector
Here, are some features of the radiation detector device that is worth mentioning. 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 NIST Calibration Additional

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
