Ranger EXP Multifunctional nuclear radiation detector Description：

Datasheet Procedures

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!

Internal memory and the free Observer USB Software (Windows® only) allow you to download your data, and set computer alarms. With the optional Blue Tooth module you can download Free Radiation Alert® Observer BLE app from the Google App Store, where you can display the readings from your detector on your android device, label sample readings and descriptions, take timed counts, append GPS data and send your saved survey file. Alarms set on the instrument will also activate on your android device.

Applications & Uses: Surveying for NORM (Naturally Occurring Radioactive Material) contamination, Gross wipe counting, Contamination surveys of packages, equipment, people, etc., Regulatory inspections, Scrap Metal Screening, Low energy radionuclide detection

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 ( ₃₅ S)、Strontium ( ₉₀ Sr/y)、Cesium ( ₁₃₇ Cs)、Phosphorus ( ₃₂ P)、Carbon ( ₁₄ C)、Iodine ( ₁₃₁ I)、Cobalt ( ₆₀ Co) and Alpha
Accuracy	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.
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
