Radiation Detector
Inspector+ & Inspector EXP+

INSPECTOR+
The Inspector+ is a small, handheld, microprocessor-based instrument 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, external calibration controls and a settable alert.
Detector
Inspector+ (Internal tube)
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.).
Radiation symbol on front label marks the center of the detector.
Inspector+ EXP (External probe)
RAP-RS1 Probe:
Same GM tube as Inspector+. Anodized aluminum housing with coated, black foam grip. 500-volt power supply is in the probe head.
Size- Approx. length: 22.2 cm (8.75 in.) Diameter: 7 cm (2.75 in.)
Connector - Amphenol tuchel connectors
Display:
4 digit liquid crystal display with indicators.
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 Accuracy:
  • mR/hr- 0.001 (1µR) to 100 mR/hr
  • µSv/hr- 0.01 to 1000
  • CPM - 0 to 350,000
  • CPS - 0 to 5000
  • Total/Timer - 1 to 9,999,000 counts
 mR/hr +/- 10%- 0 to 100
µSv/hr +/- 10% 01 – 1000
CPM +/- 10% 0 to 350,000
(Referenced to Cs-137)

Alert Set Range:
mR/hr .001 - 50 and CPM 1 - 160,000
Gamma Sensitivity:
3500 CPM/mR/hr referenced to Cs-137. Smallest detectable level for I-125 is .02 µCi at contact.
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:
Dual miniature jack drives CMOS or TTL devices: count to computer or datalogger. Submini jack input allows for electronic calibration.
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.
Temperature Range:
-10ºC to 50ºC (14ºF to 122ºF).
Weight: Inspector:
 301.4 grams (10.6 oz.) without battery. Inspector EXP: 420 grams (1 lb. 15.6 oz.) without battery.
Size:
 150 x 80 x 30 mm (5.9 x 3.3 x 1.2 in.).
Utility Menu:

The Utility Menu offers several options accessible by holding down the + button while turning the instrument on.

  • 3 second (fast response)
  • Switches from mR/hr and CPM to µSv/hr and CPS
  • Reset the cal factor to 100.
  • Probe adjustment settings.
  • Adjust the CAL factor.
  • Reset all setting to original factory setting (default).
Includes:
Carrying Case, Cable for Inspector+ EXP: 42-inch Beldon 9853 with Amphenol 31226 twinax.
Options:
 Observer Software, STAND and Wipe Test Plate.
Warranty: 90 day Warranty on GM Detector, 1 year limited warranty and CE mark.

WipeTest Plate (patent #5,936,246)
The stainless steel WipeTest Plate slides easily onto the Inspector 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 or decontamination. It can also be used for protecting the GM from damage and the instrument from being contaminated while the Inspector is not in use.
