With the patented screw press technology, high pressure can be easily generated, as well as increased and decreased smoothly down to 85% vacuum. With no check valve (non-returning valve), the 925 and 927 avoid the troublesome leakage issues that is usually experienced with most hand pumps and allows for minimal maintenance. The 928 incorporates a dual-piston system which is ideal for filling large volume workload with the hand pump and providing smooth increase and decrease of pressure with the fine adjustment. The Additel 928 Test hand pump incorporates an isolation valve which isolates the calibration volume from the check valve associated with the hand pump. Two hand-tight quick connectors installed on the pump allow easy connecting and disconnecting to the test pump without the need for PTFE tape or wrenches. The 925, 927, and 928 are ideal comparison test pumps for calibrating pressure measuring instruments such as test gauges, indicators or transducers in the field or laboratory.
