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.

1.Quickly alerts first responders to the presence of harmful levels of nuclear radiation

2.Improves safety in the laboratory and in the field

3.Automatically compensates for GM tube dead time

4.Will not jam in high radiation fields

5.Meets CE certification requirements for Europe
