Description

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, digital instrument which offers excellent sensitivity to low levels of alpha, beta, gamma, and x-rays. It 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
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 Cs-137)
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 (Cs-137). Smallest detectable level for I-125 is .02 µCi at contact.

Built-In Efficiencies
Sulfur (S-35), Strontium (Sr/Y-90), Cesium (Cs-137), Phosphorus (P-32), Carbon (C-14), Iodine (I-131), Cobalt (Co-60), 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)
