Environmental Laboratory Nuclear Detector - JB4100

Environmental Laboratory Nuclear Detector Introductions

JB4100 is a α-β surface contamination detector.It apply to low α, β radiation surface contamination detection. Dual-flash detector apparatus with high detection efficiency; the same probe can simultaneously measuring α, β, and automatically distinguish between α and β particles.

For environmental laboratory, nuclear medicine, molecular biology
Material science, radiochemistry, nuclear materials transport, storage and inspection areas such as α, β radiation surface, it's the ideal instrument for pollution detection.

The instrument use MCU control, continuous data collection, Storage, and are free to query.
