辐射仪Handheld Surface Contamination Meter

 

 

The Inspector Alert measures alpha, beta, gamma and x-radiation using a 2-inch "pancake" GM detector with high sensitivity to common beta and alpha sources.

The easy-to-read digital display shows readings in your choice of mR/hr, CPM, CPS, or µS/hr. The Total/Timer feature allows timed readings from one minute to 24 hours for precise measurement of low level contamination. An audible alert sounds when the radiaiton reaches a user-adjustable level.

  • Quickly alerts first responders to the presence of harmful levels of nuclear radiation
  • Improves safety in the laboratory and in the field
  • Automatically compensates for GM tube dead time
  • Will not jam in high radiation fields
  • Meets CE certification requirements forEurope
