The IMI Inspector Alert™V2 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 reading in your choice of Dose Rate - µSv/hr or mR/hr, and Count Rate - CPM or CPS. The Total I Timer feature allows timed readings from one minute to 40 hours for precise measurement of low-level contamination. An Audible alert sounds when the radiation reaches a user-adjustable level. -Quickly alerts user to the presence of harmful levels of nuclear radiation -Detects noble gases and low energy radionuclides -Automatically compensates for GM tube dead time -Will not jam in high radiation fields -Meets CE Certification, RoHS compliant and WEEE standards
