Surveymeter Digital Inspector (Inspector Handheld Digital Radiation Alert® Detector a ß y x)

17 Mei 2013


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 adjustable alert. 
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 (1.75 in.). Radiation symbol on front label marks the center of the detector.

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

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 end window. 3340 CPM/mR/hr (Cs137). Smallest detectable level for I125 is .02 µCi at contact.
Operating Range
mR/hr - .001 (1µR) to 100
CPM - 0 to 350,000
µSv/hr - .01 to 1000
CPS - 0 to 5000
Total/ Timer - 1 to 9,999,000 counts
Accuracy
mR/hr ±10% typical (NIST), ±15% max - 0 to 100
µSv/hr ±10% typical (NIST), ±15% max - .01 - 1000
CPM ±10% typical (NIST), ±15% max - 0 to 350,000
(Referenced to Cs-137)
Alert Set Range
mR/hr .001 - 50 and CPM 1 - 160,000. 70db @ 1m.
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 approx.
2160 hours at normal background.
Temperature Range
-10ºC to 50ºC (14ºF to 122ºF)
Weight
Inspector: 273 grams (9.6 oz.) without battery.
Size
150 x 80 x 30 mm (5.9 x 3.1 x 1.2 in.).
Includes
Carrying Case, CE Certification
Options
Observer Software, Xtreme Boot, Waterproof Case (Gamma & X-Ray Only), & Wipe Test Plate
Limited Warranty
1 year limited, 90 day Warranty on GM Detector
