Description

The Ranger Radiation Survey Meter by SE International

The Ranger offers maximum performance in a lightweight, rugged solution for surveying at the facility or in the field. The Ranger has been designed for industrial environments, but it still has all of the features you�ve come to love in the lab. The Ranger 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!

Specifications

Detector	Internal 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 - .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. 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 Display 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 for PCs
Power Requirements	Two AA alkaline batteries (included). Approx. 800 hrs @ background
Temperature Range	-10° to 50°C (14° to 122°F)
Size	140 X 68 X 33 mm (5.5 X 2.7 X 1.3 in.)
Weight	10.3 oz (0.64 lbs.)
Includes	Carrying Case, Xtreme Boot, Lanyard, Stand, Batteries, Mini-USB Cable, Observer USB Software Download, Certificate of Conformance
Options	Wipe Test Plate, Swipes, NIST Calibration
Limited Warranty	1 year limited warranty
