W-HB 011(Original)





The tester is designed to calibrate pressure gauge.
It consists of a precision machined stainless steel piston and cylinder with calibrated weights. The weights are applied on the upper end of the piston rod to generate pressure. The assembly is mounted on adjusting screws with a bull’s eye level. The pressure gauge is connected to the cylinder, thus subject to known pressure and comparison with the gauge reading can be made. Leaking liquid from the cylinder is returned to a reservoir. The cylinder can be simply refilled with liquid from the reservoir without removing the piston.
Instruction manual is also included.
