Inspector EXP Radiation Detector

Pocket Digital Radiation Detector with External Pancake G-M Probe

Discontinued - replaced by the "Ranger EXP"

The Inspector EXP Radiation Detector was designed for general purpose survey of alpha, beta, gamma and x-ray. It has the same valuable features, small size, and quality of the Inspector, but features the added versatility of an external probe. The carrying case has a clear window panel providing full view of the readout, count light, and access to the switches. Convenient hand straps and a belt loop are provided for carrying the instrument. A small pocket is provided for a check source. The unique design of attaching the probe to the carrying case allows one-handed operation if desired. The protective probe cover folds easily out of the way during one-handed operation.
