SEI Inspector EXP / Digital Radiation Detector - a ß y x
SEI Inspector EXP /数字辐射探测器 - a ß y x
Now with USB and the free Observer USB Software, you can download your data from the internal memory, set computer alarms, and calibrate your instrument! The SEI Inspector EXP offers maximum performance in a lightweight, rugged solution for using your survey meter in the field. The SEI Inspector EXP is designed specifically for individuals operating in tough environments, such as 1st Responders, miners, and HAZMAT crews. The unit 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 selectable alert.
Detector
External Halogen-quenched, uncompensated GM tube with thin mica window, 1.4-2.0 mg/cm2 areal density. Effective diameter of window is 45 mm (1.77 in.). Radiation symbol on front label and end panel marks the center of the detector. Additional features include backlight display, internal memory, built-in efficiencies for common isotopes, and free Observer USB Software.
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 (Referenced to Cs137)
Typically ±15% from factory, ±10% with NIST Source Calibration
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.
Selectable Alert Set Range
mR/hr .001 - 50 and CPM 1 - 160,000. 70db @ 1m. Pulsating beeper sounds the alert. Adjustable alert levels are used for mR/hr / CPM, and µSv/hr / CPS. Alarm will sound when in Timer Mode when set alarm threshold is reached.
Anti-Saturation
Meter will hold at OVER RANGE in fields as high as 100 times the maximum reading.
Averaging Periods
Display updates every 3 seconds. At low background levels, the update is the average for the past 30-second time period. The timed period for the average decreases as the radiation level increases.
Display
Backlit 4 digit liquid crystal display with indicators. Display updates every 3 seconds.
Count Light
Red LED flashes with each radiation event.
Audio Indicator
Internally mounted beeper (can be switched off for silent operation)
Outputs
3.5mm jack for CMOS or TTL devices and counts to computer or datalogger.
USB for use with Free Observer USB Software for PCs
