WB Johnson GP-1003

WB Johnson Energy Compensated GM Probe

The GP Series detectors are excellent detectors for general gamma monitoring. Its small size and rugged design make the GP Series Detectors some of the most durable and reliable detectors available.

The GP-1003 is for reading higher gamma fields than the GP-1002, but less than the GP-1004
