The Ametek HydraLite hydraulic deadweight tester is designed as an easy-to-use primary standard capable of high accuracy whether in the lab or in the field. The Ametek HydraLite hydraulic deadweight tester is available in either single or dual cylinder models to meet a variety of calibration needs. The HydraLite is also available in a gauge version for those requiring precision pressure measurements or a comparison standard. The gauge version can be converted to a tester with an optional accessory kit.

Ametek HydraLite hydraulic deadweight testers are of a superior design utilizing overhung weight carriers to reduce side thrust and friction, die-cast aluminum and alloy weights, and a re-entrant piston / cylinder to reduce fluid leakage and increase float time. A screwpump pressure source on the tester model offers a convenient method to raise and lower pressure for rapid testing. The Ametek HydraLite hydraulic deadweight tester is manufactured using brass and aluminum components, AAA Tester Oil is the recommended and supplied pressure media. Other fluids compatible with stainless steel, brass, aluminum, and Buna may be used.

Ametek HydraLite deadweight testers and gauges are available in psi, bar, kg/cm2, and kPa with ranges up to 3000 psi or equivalent and accuracies of ±0.100% or ±0.050% of reading. The accuracy stated is the overall accuracy of the tester. The accuracy takes into account linearity, hysteresis, and repeatability. It would also account for intrinsic corrections. The Ametek HydraLite hydraulic deadweight tester is manufactured to International Standard Gravity (9.80665 m/s2), and a local gravity site correction is easily performed with a ratio correction to the output.
