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 µSv/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 radiation reaches a user-adjustable level.
The Inspector Alert is ideal for anyone wanting the capability to quickly and accurately detect surface contamination just about anywhere.
•  Quickly alerts first responders 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 for Europe
