The ASM-990 series are easy-to-use instruments that detect alpha, beta, gamma, neutron, or x-ray radiation within an operating range of 1 ตR/hr to 1 R/hr or 1 to 5,000,000 CPM, depending on the probe selection. Visual indication of measured values, as well as selectable parameters, are displayed on the analog/digital display.

The units are compatible with Geiger-Mueller (GM) detectors, neutron probes, proportional counters, and scintillation probes operating from 500 to 1300 volts.


The ASM-990 series are designed to meet the high technology requirements of health physics, medical physics, and nondestructive testing applications. Radiation safety officers (RSO), nuclear medicine laboratories, diagnostic xray and hospital emergency room technicians, and environmental health physicists will appreciate this intelligent survey meter with its cell phone-like multi-function key for easy menu navigation.

The units, with purchased probe, are shipped calibrated and ready-to-use. With the proper probe combination, this meter can be used as a general survey meter, an area monitor, a wipe test counter, and a contamination monitor.

The unit is supplied with a MHV connector to ensure compatibility with all Victoreen probes. A Model 992 is available that includes a fully calibrated internal energy compensated 1 R/hr GM detector. The Model 993 features a fully calibrated internal pancake detector as well as an internal energy compensated 1 R/hr GM detector.
