     PNEUMATIC DEADWEIGHT TESTER

Description:

dead weight tester as a pressure resource of pressed air and Nitrogen.It is 

pneumatic loaded pressure calibrator to use the floating ball.

It is a kind of pressure Benchmark instrument, with nitrogen or instrument compressed air as energy. 

it's an ideal equipment that calibrate all kinds of high accuracy of pressure transmitter, differential transmitter 

and precision of pressure gauge.
