Ametek M and G HK series Deadweight Tester
Ametek M and G HK series Deadweight Tester SKU:AM_DW_HK
Description and Specs
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)

Accuracy
to 0.025% of Indicated reading

Repeateability
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.
