产品介绍
Inspector是小的手持式微处理器控制的高灵敏度低水平能检测Χγαβ射线。直接读出射线水平。另外，有可调整的定时器和外部校准键。
检测器：
具有云母窗口的GM管，窗口有效直径45 mm
Inspector （只有内部GM管）
在前面板中心有射线标记标记
Inspector EXP（只有外部探头）
在仪器外部具有把手，有与Inspector相同的GM管探头。
电源要求：一节9V碱性电池。电池寿命200小时
该剂量仪采用一支盖革-弥勒计数管来测定αβγ及Χ射线辐射，数字显示，探头为内置式，使体积更小灵敏度更高。
技术指标：
剂量率：mR/hr（毫伦/小时） 0.001～100μSV/ hr（微希伏/小时） 0.01～1000
计数：CPM（每分钟计数）0～300000 CPS（每秒钟计数）0～5000
计数时间选择：为了精确测量低计量的α线和β射线可选择1分-24小时
连续计数再除以计数时间变为CPM或CPS
精度：<±15%
重量：272g
体积：150×80×30㎜

Inspector Handheld Digital Radiation Alert® Detector a ß y x
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
