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.
- 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 for Europe

Averaging Periods: Display updates every 3 seconds, showing the average for the past 30-second time period at normal levels. The averaging period decreases as the radiation level increases. User can select a fast 3-second averaging period.
Timer: Can set 1-10 minute sampling periods in one-minute increments, 10-50 minute sampling periods in 10-minute increments, and 1-24 hour sampling periods in 1-hour increments
Alert: Beeper sounds the alert
User-adjustable alert level is set using three buttons
