NATO-approved handheld ratemeter for gamma and neutron radiation, ruggedised for the military and first responders, with an external probe for alpha, beta and gamma contamination.
The SVG2 is a lightweight, battery-powered ratemeter with low power consumption, designed for measurements after nuclear incidents or attacks. It displays both the current gamma dose rate and the integrated gamma dose, on a large backlit LCD with an analogue trend indicator and digital readout.
The SVG2 System consists of three groups: the SVG2 Kit, a Supplementary Kit for measuring samples, and a Radiation Protection Kit with an NBR probe for high-sensitivity detection of hidden gamma sources and alpha and beta contamination.
