JUST IN! HFS-20 Personal Geiger Dosimeter, £65.00 inc. UK Shipping*

Introducing the remarkable HFS-20 and it has to be one of the most well equipped, and affordable personal radiation monitors we’ve seen in a long time.

This cute little instrument, smaller than a well used bar of soap (we’re trying to avoid comparing things to packs of cigarettes…) is a fully featured dosimeter, sensitive to hard Beta, Gamma and X-Rays. The large (48mm/2-in) backlit colour LCD display shows dosage in real time (0.08 μSv/h – 50mSv/h), average dose rate (μSv/h) and accumulated dose (μSv/h). Time and date-stamped measurements can be recorded - directly or scheduled - and stored on its internal memory. The user-set alarm has audible and visual indicators, an event ‘clicker’, Sleep mode and there’s another seriously big plus point: The built-in rechargeable Lithium battery can keep it operating continuously for up to 15 days.
By the way it comes with a USB charge cable (type C plug), a wrist strap and an instruction leaflet, not that you really need it. It really is incredibly simple to use with just three buttons controlling the icon-based on-screen menu providing easy access to all key functions.
