The InspectorAlert
Handheld Surface Contamination Monitor
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 or μSv/hr, CPM, or CPS. 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 meets CE certification requirements for Europe. |
