S.E. International Inspector EXP B008KRO6QO Leaflet

The Inspector EXP was designed to meet the requirements of emergency response personnel. New 

added features include a backlit display, built-in efficiencies for common isotopes, on-board memory, 

USB, and free Observer USB Software! It delivers the same quality you’ve come to expect from the 

Inspector USB, but instead of the built-in detector, it has the added versatility of an external probe. 

The carrying case has a clear window panel providing full view of the readout, count light, access to 

the switches, and a convenient belt loop for carrying the instrument.

 areal density. Effective diameter of window is 45 

mm (1.75 in.). Radiation symbol on probe marks the 

center of the detector.

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

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 

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
