Description  more details

The Ranger is a small, handheld microprocessor-based radiation detector which offers excellent sensitivity to 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 and external calibration controls.

The external version of the RANGER has the GM detector in a hand held "lollipop". The electronics unit is held in a case with shoulder strap or belt clip.

Wipe Test
The stainless steel WipeTest Plate slides easily onto the RANGER positioning the depression and wipe directly in front of the GM tube window at a fixed distance of 1 centimeter. The WipeTest plate is removable for general surveying. (patent #5,936,246) Many of the customers using The RANGER Wipe Test Plate also use it as a Beta Shield for the 2-inch GM detector.

Xtreme Boot
The Xtreme boot offers maximum performance in a lightweight rugged solution for using Radiation Alert® products in the field. The Xtreme boot is designed specifically for individuals operating in tough environments, such as 1st Responders, Mining and HAZMAT crews. Made of a RoHS compliant TPE rubber, the case also offers superior grip and drop protection. When using the pancake detector, a protective door opens on the back of the case exposing the end window of the GM for alpha detection. The Xtreme boot is designed for use with the ranger and Digilert handheld radiation detectors. (A soft case is included with the stardard instrument.)

Observer Software
The software provides a virtual interface to your Ranger on your PC. The software reads in count, CPM and CPS and has the ability to collect, log and perform statistical analysis on the data received. The data is displayed on a graph as well as digital and analog on screen meters. It can be saved printed and exported to spread sheets. The dwell/count rate can be adjusted or each point on the graph. You can also set the time duration you want to count for. The virtual meters on the screen have adjustable settings and alarms and there are both visual and audio indicators - you can play the meter click through your PC speakers

Detector Halogen-quenched, uncompensated Geiger Muller tube with thin mica window, 1.4-2.0 mg/cm2 areal density.
Effective diameter of window is 45 mm (1.75 in.).
Ranger
(Internal tube only)		 Radiation symbol on front label marks the center of the detector.
Ranger EXP
(External probe only)		 Same GM tube as Ranger. Anodized aluminum housing with coated, black foam grip
External 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 (1.75 in.).
Display: Graphic Display with backlight
Averaging periods: Display will update every 3 seconds. At low background levels, the update is the moving average for the past 30-second time period. The timed period for the moving average decreases as the radiation level increases.
Operating Range: mR/hr - .001 (1µR) to 100 mR/hr
µSv/hr - .01 to 1000
CPM - 0 to 350,000
CPS - 0 to 5000
Total/ Timer - 1 to 9,999,000 counts
Accuracy (Referenced to Cs137) Typically ±15% from factory, ±10% with NIST Source Calibration
Energy Sensitivity 3340 CPM/mR/hr referenced to Cs137
• 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 end window.
Smallest detectable level for I125 is .02 μCi at contact.

(Cs137), 32Phosphorus (P32), 14Carbon (C14),
131Iodine (I131), 60Cobalt (Co60), and Alpha
Timer Can set 1 minute sampling periods from 1 to 10 minutes. 10 minute sampling periods 10- 60 minutes. 1 hour sampling periods from 1 to 24 hours.
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
Anti-Saturation Meter will hold at full scale in fields as high as 100 times the maximum reading.
Power Requirements One 9-volt alkaline battery. Battery life is min. 200 hours at normal background radiation levels.
