The ASM-990 series can detect alpha, beta, gamma, or x-ray radiation within an operating range of 1 uSv/hr to 1 R/hr (1 to 5,000,000 CPM), depending on the selected probe (Geiger-Mueller, neutron, proportional counter, scintillation).

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.

Designed to meet the high technology requirements of health physics, medical physics, and nondestructive testing applications, the ASM-990 Series is well-suited for a wide range of end users, including: Radiation safety officers (RSO), nuclear medicine laboratories, diagnostic x-ray and hospital emergency room technicians, environmental health physicists, and emergency responders.

The units, with purchased probe, are shipped calibrated, ready-to-use, and include a MHV connector to ensure compatibility with all Fluke Biomedical probes. The 992 includes a fully calibrated internal energy compensated 1 R/hr GM detector. The 993 features a fully calibrated internal pancake detector as well as an internal energy compensated 1 R/hr GM detector.
