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.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).

• Pressure Range
  50 to 10,000 kPa (10 to 1500 psi)
• Accuracy to ±0.025% of Indicated reading
• Repeatability ±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 self-regulating calibrations at high pressures without leaving a hydraulic residue in the UUT.
