Air: -6psi to 6psi
Designed for low pressure application requiring accurate low pressure testing and calibration. It can be used in calibrating low pressure gauges, transmitters, or other pressure measuring instruments.
Only 1.6kg
0.1Pa (0.001 mbar); Specially designed screw press for fine pressure adjustment.
Great StabilityIsothermal chamber: the pressure chamber is insulated to reduce the influence from environmental temperature changes. Specially designed bellows minimize leakage to guarantee excellent stability.
Durable and Minimal Maintenance
Without non-returning valve that is usually used on troublesome hand pump.
Easy-to-use
Pressure could be set and adjusted precisely and quickly through a simple turn of the handle.
Hand-tight Quick Connectors
Allows easy connecting and disconnecting to the test pump without the need for PTFE tape or wrenches.
