Introduction
This general
purpose, handheld analog ratemeter supports GM, proportional and scintillation
type radiation detectors. The aluminum cast instrument housing with its separate battery
compartment and accompanying metal handle offer an industrial robustness and
quality that promote long lasting protection and instrument life. The front
panel controls include a rotary switch for selecting the 4 decade range,
instrument shut off and battery test, an audio on/off switch, a fast/slow
response switch, a high voltage display button, a count reset button and a 3
position detector HV selector switch. The analog meter face comes in a variety
of options to support the measurement units and ranges for the additional
external detector selected. A 39" long straight type detector cable with "C"
style connector is include in the price of the instrument.

Compatible Radiation Detectors
Compatible radiation detectors are listed below and are
not included with the survey meter price. An additional charge will be added for
each detector ordered.
*For Mylar window scintillators it is strongly
suggested that the optional
overload indicator be used on the Model
18 Radiation Analyzer to better determine the presence of a light leak.
