该检测仪用于测量α、β、γ及X射线的辐射。它的数字液晶显示屏能够显示当前的辐射水平范围在0.001到110毫伦伏/小时或者是0到350000cpm（每分钟计数）。当 SI 单位被选择的时候，液晶显示屏显示的读数从0.01到100微希伏/小时或者是0到3500cps（每秒计数）。这个仪器同时也提供一种非常精确的计数和定时功能。计数范围可以从0到9999000，而定时最大可定40小时。每计数一次，红色的发光二级管都会闪亮并伴随着发声仪发声（声音大小可调）。当辐射水平达到用户所设定的水平的时候，可听得见的报警器就会响。
适用场所：
● 监测人身的放射性暴露量 ● 监测一个地区的边界周长
● 探测放射性泄露和污染 ● 确保可调整

Inspector Alert
Inspector Alert Handheld Surface Contamination Meter
How to Use the Inspector Alert
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
