Inspector exp radiation detector
The Inspector is a small, handheld microprocessor-based instrument
that 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 sound with each count detected. Other features include an
adjustable timer and external calibration controls.
The Inspector EXP was designed for 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 with a convenient carrying case that attaches to a belt or
