輻射表/數顯輻射檢測儀Inspector EXP
- 主要規格：
- Inspector/Inspectro EXP/monitor 4EC
- 產品介紹 :Inspector是小的手持式微處理器控制的高靈敏度低水平能檢測Χγαβ射線。直接讀出射線水平。另外，有可調整的定時器和外部校準鍵。
檢測器：
具有云母窗口的GM管，窗口有效直徑45 mm
Inspector (只有內部GM管)
在前面板中心有射線標記標記
Inspector EXP(只有外部探頭)
在儀器外部具有把手，有與Inspector相同的GM管探頭。
電源要求：一節9V堿性電池。電池壽命200小時
該劑量儀采用一支蓋革-彌勒計數管來測定αβγ及Χ射線輻射，數字顯示，探頭為內置式，使體積更小靈敏度更高。
技術指標：
劑量率：mR/hr(毫倫/小時) 0.001～100μSV/ hr(微希伏/小時) 0.01～1000
計數：CPM（每分鐘計數）0～300000 CPS（每秒鐘計數）0～5000
計數時間選擇：為了精確測量低計量的α線和β射線可選擇1分-24小時
連續計數再除以計數時間變為CPM或CPS
精度：<±15%
重量：272g
體積：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.
