Pneumatic calibration pump ADT 901

manualfor pressure generationlow-pressure

Description
The ADDITEL ADT 901 pneumatic hand pump is a manual device for generating and controlling pressure in the range -0.4 to 0.4 bar (-6 to 6 psi). A fine adjustment screw provides pressure setting resolution of 0.001 mbar. The pump features enhanced stability through a reduced isothermal chamber that minimizes the influence of ambient temperature. Its design omits a check valve to improve stability and reduce maintenance operations. Two hand-tighten connections allow quick attachment and removal of gauges without sealing tape or wrenches. The pump is suited to very low-pressure applications and the calibration of transmitters and gauges in the field or laboratory.
