Handheld X-ray detector from the US Inspector

brief introduction
·The Inspector detector can be used to detect alpha, beta, gamma, and X-rays
·The built-in 2-inch flat GM detector has high sensitivity to alpha and beta radiation sources
·Digital displays can choose different units such as mR/hr, CPM, CPS, or mSv/hr as needed
·The detector automatically compensates for the dead time of the GM tube, and the anti saturation circuit prevents interference in strong radiation fields
·The detector meets the CE certification requirements in Europe
·The detector can detect minor pollution and perform timed readings
·The time setting can range from 1 minute to 24 hours, and calibration based on the standard of "safety * * *" can avoid the harm of radiation leakage to calibration personnel

technical specifications
·Detector halogen quencher GM tube, effective diameter 45mm, mica window density 1.5-2.0 mg/cm3
·The four digit value is displayed on the LCD screen, and the counting light is a red LED light
·The average cycle is updated every 3 seconds, displaying the average value of the previous 30 seconds. If the radiation intensity increases, the average period of 30 seconds will be shortened. Users can choose the shortest average cycle of 3 seconds
·Operating range 0.001 to 100.0 mR/hr, 0 to 300000 CPM, total count 1 to 9999000; 0.01 to 1000 μ Sv/hr, 0 to 5000 CPS
·The efficiency of Sr-90 (546KeV, 2.3MeV β max) is about 75%; The efficiency of C-14 (156KeV β max) is about 11%
·The efficiency of Bi-210 (1.2 MeV β max) is about 64%; The efficiency of Am-241 (5.5 MeV α) is approximately 36%
·The timer can be set to receive radiation for 1 to 10 minutes, with a unit increment of 1 minute; Or 10-50 minutes, with a unit increment of 10 minutes; Or 1-24 hours, with a unit increment of 1 hour
·Power supply: 1 9V alkaline battery, which can last for 200 hours under natural conditions and at least 24 hours under a dose rate of 1 mR/hr
·Output dual micro jack driver CMOS or TTL program, which can download data to the computer. Micro jack allows for electronic calibration
·The anti saturation reading device can display up to 100 readings at full scale on site
·The sound has corresponding sound prompts and can be set to mute
·Volume and weight 150 × 80 × 30 mm, with battery 350 g
·Sensitivity of 3500 CPM/mR/hr for 137Cs standard source
·Accuracy ± 15%
·The ambient temperature ranges from -10 to+50 ° C
·Optional erasable inspection panel, external scintillator probe
Inspector EXP type detector
·The Inspector EXP detector is designed for personal emergency use
·Similar to the Inspector detector, it has the same characteristics of small size and good detector quality; But it uses an external probe
·There are also some functional features of external probes
·There is a clear and transparent window on the portable instrument box, through which the entire counter reading can be seen
·At the same time, it can also adjust the control switch
·The instrument box also includes a convenient cover, a belt ring, and a small bag containing a calibration source
·If necessary, the detector can be attached to a portable instrument box for one handed operation
·The detector protective cover can be easily folded up for easy operation
·The detector is the same as the inspector
·The housing is plated with aluminum and equipped with black coated foam handle
·Power supply 500V, placed at the head of the detector
·Volume length 22.2 cm, diameter 7 cm
·Connect Amphenol 31226 twinax connection
