Dirt Trap
Mesnor calibrator dirt trap

The CPH7650 should only be used with dry and clean test items. Soiling of the integrated pump, for example, through contaminated test items, can lead to faults on the pump or require the pump to be cleaned. The dirt trap helps to prevent contamination of the integrated pump
