Dwyer-Dead Weight Tester-HJi

( Dwyer )

General
The AMETEK HK Pneumatic Deadweight Tester is a primary standard used to calibrate pressure and differential pressure gauges, transmitters, transducers, recorders and controllers, and that can provide a reference pressure in process control applications. The HK tester is self-regulating with accuracy independent of the operator. These testers feature superior accuracy and repeatability and a prefill feature that minimizes the filling of large static output volumes before the test. Accurate to +0.025% of Indicated Reading Ranges- 10 to 300 PSIG 10 to 500 PSIG 10 to 700 PSIG 10 to 1000 PSIG 10 to 1500 PSIG Prefill Supplied for Quick Filling Large Static Output Volumes NIST Traceable
