The 1042WM, 1046WM, and 1056WM Universal Digital Ratemeters (UDR) are 2nd generation digital radiation monitoring instruments capable of being directly interfaced to pulse producing or low current producing detectors and displaying the radiation signal in various engineering units; (CPM, mR/h, μCi/cc, etc.). The 2nd generation of Victoreen digital instrumentation is inherently more reliable and requires less maintenance than the 1st generation digital equipment. The UDRs are capable of being interfaced to a computer system, via the digital communications port, and can be used as a local controller. Victoreen’s 1042WM, 1046WM, and 1056WM UDRs are designed to achieve a high degree of reliability and are qualified for use in nuclear safety related applications.
