The Inspector is a small, handheld microprocessor-based instrument which offers excellent sensitivity to low levels of alpha, beta, gamma, and x-rays. The digital readout is displayed with a red count light and a beeper sounds with each count detected. Other features include an adjustable timer and external calibration controls.

The stainless steel WipeTest Plate slides easily onto the Inspector positioning the depression and wipe directly in front of the GM tube window at a fixed distance of 1 centimeter. The WipeTest plate is removable for general surveying or decontamination. It can also be used for protecting the GM from damage and the instrument from being contaminated while the Inspector is not in use.
