CW28 N

alpha, bta, and gamma 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.
