LB 124 SCINT

Details

The contamination monitor LB 124 SCINT is a portable battery-operated measuring device. It consists of a display unit with microprocessor electronics, signal processing electronics and a ZnS scintillation detector with photomultiplier with an active measuring area of 170 cm2. Due to a sophisticated reflector geometry, the device has an extremely uniform response over the entire surface. The device has guides on its underside. These allow the attachment of an additional protective grid or the use of an accessory drawer for activity measurements of small samples.
