Ametek HK [HK-100B/C] Pneumatic Deadweight Tester, ±0.025% of Reading Standard or Local Gravity w/ Calibration Report, 0.5 to 100 bar (0.1 bar increments)

The Ametek HK pneumatic deadweight tester is a primary standard used to calibrate pressure and differential pressure gauges, transmitters, transducers, recorders and controllers. The Ametek HK pneumatic deadweight tester is designed for precision and is accurate enough for lab use, however, the construction is rugged enough to allow for reliable field operation as well.

The Ametek HK pneumatic deadweight tester produces pressure by applying force (weight set) over area (the ceramic ball and nozzle). While in operation, the Ametek HK pneumatic deadweight tester's ball and weights float freely, supported only by a thin film of air which is virtually frictionless. This eliminates the necessity to rotate the weights during testing and allows the user to concentrate on the instrument
