NMS017NG3

Hand-held, Dose Equivalent Neutron Monitor

The NMS017NG3 is the latest generation of neutron monitor from John Caunt Scientific Ltd. It is a battery-powered hand-held neutron survey monitor that provides ambient dose equivalent measurements from thermal to 14MeV neutrons.

Ease of use and deployment underpin the design philosophy of the NMS017NG3 and has seen this instrument adopted as the industry standard deployed across the majority of civil nuclear sites, AWE, MoD as well as many academic, research and medical establishments.

This latest neutron monitor incorporates a digital display, providing a user-friendly visual display of dose rate as well as numeric feedback. The LCD display can be read in all light conditions and has vastly improved the battery life (>120hrs). Measurement modes include dose rate, accumulated dose, count rate and various count and time modes for integrated measurements.
