Contamination monitors

CW28 N

α, β and γ floor contamination monitor

The CW28 N is designed to monitor floors contamination.

It has been specially developped for Alpha, Beta and Gamma simultaneous contamination control on small and large surfaces.

The α, β and γ particles are simultaneously detected and discriminated.

Automatic background compensation is performed.

The device can be moved around very easily thanks to its 4 rotating wheels.

Including a high-sensitivity large surface detector, the CW28 N operates without integrated gas bottle, but with batteries, and has therefore a long lifetime.
