Harpellassociates

Now with a settable alert, 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
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
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 min

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 2160 hours at normal background.

Temperature Range
-10ºC to 50ºC (14ºF to 122ºF)

Weight
Inspector: 301.4 grams (10.6 oz.) without battery.

Size
150 x 80 x 30 mm (5.9 x 3.3 x 1.2 in.).
