Continuous air monitoring and alpha beta counting - Series CAM
The measurement of alpha (and beta) particles from filters associated with continuous air monitors.
The same device is ideal for measuring filter samples off-line providing excellent alpha beta separation.
CAM-Series: 300 to 2000mm² with minimum 140µm to 500µm active thickness
