Advanced Survey Meter (ASM)
Victoreen« ASM-990

Introduction
The ASM-990 is an easy-to-use instrument that detects alpha, beta, gamma, neutron, or x-ray radiation within an operating range of 1 ÁR/h to 1 R/h or 1 CPM 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 ASM-990 is compatible with Geiger-Mueller (GM) detectors, neutron probes, proportional counters, and scintillation probes operating from 500 to 1300 volts.

Applications
The ASM-990 is designed to meet the high technology requirements of health physics, medical physics, and nondestructive testing applications. Radiation safety officers (RSO), nuclear medicine laboratories, diagnostic x-ray 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 unit is supplied with a MHV connector to ensure compatibility with all Victoreen probes. In addition, a Model 992 is available that includes a fully calibrated internal 1 R GM detector.

The ASM-990, with purchased probe, is shipped calibrated and ready-to-use.
