Product Specifications Thermo Scientific EPD Mk2+ combines unequalled radiological performance with advanced software and hardware features. Thermo Scientific EPD Mk2+ Electronic Personal Dosimeter Key Features • Advanced radiological performance, 15 keV to 10 MeV, in a small, lightweight design •Most complete dosimeter per IAEA Active Personal Dosimeter Intercomparison study IAEA-TECDOC-1564 • Multi-detector technology • Excellent response to gamma, beta, and X-radiation • Improved power management and battery monitoring • Loud configurable audible alarm • Excellent immunity to electromagnetic interference • Enhanced, easy-to-read display with optional backlight • Rugged battery cap and enhanced clip retention • Improved reliability of LCD and case • Additional software features provided • Single AA battery powers the unit The Thermo Scientific EPD Mk2+ builds upon the high performance of the original MK2 design, while providing enhanced features. The EPD Mk2+ is suitable for use as a single, stand-alone dosimeter, or as a component of a comprehensive dosimetry management system using our renowned hardware and software packages. The high quality of the Mk2+ provides low lifetime costs as well as advanced radiological performance. The Thermo Scientific Mk2+ electronic personal dosimeter is perfect for organizations, utilities, agencies, and research laboratories to monitor employee dose and dose rates. The Mk2+ also boasts a ruggedized battery cap and an improved display. The unit is powered by a single standard AA cell, either 1.5V alkaline or 3.6V Lithium Thionyl Chloride for maximum battery life. Pre-use integrity checks may be initiated over the IR (Infra-Red) communications link as part of the EPD Issue process of access control or dosimetry management systems. These checks include detector tests, battery test and battery voltage read. Display and function are controlled by a single button on the front of the unit, recessed to prevent inadvertent operation.
