NSN3中子仪 Neutron Survey Meter

NSN3中子仪Portable Neutron Survey Meter

The Fuji model NSN3 portable neutron survey meter is very lightweight and small without polyethylene moderator.The energy response is improved using the spectrum weighting function.

The NSN3 survey meter measures ambient dose equivalent and ambient dose equivalent rate of neutrons.

FEATURES:
Lightweight and portable(Weighs only 2kg)
Ideal for a wide range of measurements
AC power, primary and secondary cells are applicable
Equipped with USB drive function and can display measurement values on a PC
