HK Pneumatic Deadweight Tester
The AMETEK HK Pneumatic Deadweight Tester is a primary standard used to calibrate pressure and differential pressure gauges, transmitters, transducers, recorders and controllers, which can provide a reference pressure in process control applications.
Self-regulating pressure standard
The AMETEK HK Pneumatic Deadweight Tester is a primary standard that produces a pressure by applying force (weight set) over area (the ceramic ball and nozzle). The HK tester is NIST traceable and accurate to ±0.015% using stainless steel weights calibrated to International standard gravity at 9.80665 m/s2 or local gravity as specified. The HK tester is self-regulating with accuracy independent of the operator. The tester utilizes a virtually frictionless ceramic ball floating on a layer of air within a stainless steel cylinder. The HK tester features a quick-leveling system for lab setup. The unit may also be mounted on an optional tripod for more convenient setup. Weights are located in foam-protective slots in the case.
- Pressure Range
50 to 10,000 kPa (10 to 1500 psi)
to ±0.025% of Indicated reading
±0.005% of indicated reading
- Available units
psi, kg/cm2, bar, kPa
- Special Calibrations/Local Gravity
HK testers are supplied standard with masses calibrated to International Standard gravity of 9.80665 m/s2. Local gravity calibration is available on all models.
- High Pressure Pneumatic Standard
The HK is a high pressure pneumatic alternative to the available hydraulic standards. This series allows for selfregulating calibrations at high pressures without leaving a hydraulic residue in the UUT.
