CV28 N CV28 REN-D
alpha, bta, and gamma contamination monitors
CV28N flow monitors can simultaneously measure α,β and γ contamination.
Two versions of the CV28 are available:
- Stationary version : CV28 N
- Mobile version : CV28REN-D
The CV28REN-D is an autonomous and mobile contamination meter that is mounted on a cart for a better mobility.
