Radioactivity Detector Radiation Alert SE International RANGER EXP

| The Ranger EXP offers maximum performance in a lightweight, rugged solution for surveying at the facility or in the field.

| It has been designed specifically for individuals operating in tough environments.

| It's is a small, handheld, microprocessor-based instrument which offers excellent sensitivity to low levels of alpha, beta, gamma, and x-rays and has built in efficiencies for common isotopes to calculate activity in Bq and DPM.

| It has a backlit digital display, a red count light, and a beeper that sounds with each count detected.

| Other features include selectable alert levels, an adjustable timer, and an optional wipe test plate for swipes.

| Internal memory and the free Observer USB Software allow you to download your data, set computer alarms, and calibrate your instrument!

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 (1.77 in.).

Operating Range

• mR/hr - 0.001 (1µR) to 100
• CPM - 0 to 350,000
• µSv/hr - 0.01 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. Pulsating beeper sounds the alert.
• Adjustable alert levels are used for mR/hr / CPM, and µSv/hr / CPS. 70db @ 1m.
• 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).

Outputs : USB for use with Free Observer USB Software Family.

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

Size : 140 X 68 X 33 mm (5.5 X 2.7 X 1.3 in.) * Probe: 260 X 70 X 25 mm (10.25 X 2.75 X 1 in.)

Weight: 570 g (1.25 lbs.)

Includes : RAP-RS2 External GM Probe, 3 ft BNC Cable, Carrying Case, Xtreme Boot, Lanyard, Stand, Batteries, Mini-USB Cable, Observer USB Software, Observer BLE App, Certificate of Conformance.

Options : NIST Calibration Certificate.

Warranty : 1 year limited warranty.
