甚至死亡

The Inspector EXP
External Probe Surface Contamination Monitor The Inspector EXP is designed to meet the requirements of emergency response personnel. It has the same valuable features, small size, and quality of the Inspector, but instead of the built-in detector, it has the added versatility of an external probe. The carrying case has a clear window panel that provides a full view of the readout and count light and access to the switches. It includes convenient hａnd straps and a belt loop for carrying the instrument and a small pocket for a check source. The probe can be attached to the carrying case for one-handed operation if desired. The protective probe cover folds easily out of the way during one-handed operation.
