HL Hydraulic and Gauge Deadweight Tester
The HydraLite Hydraulic Deadweight Tester is a primary standard that features a re-entrant type measuring piston and cylinder assembly that helps maintain accuracy as the test pressure increases. The HL Series tester is designed for rapid interchanging between high and low pistons and is NIST traceable and accurate to ±0.05% using non-magnetic die-cast alloy or aluminum weights calibrated to international standard gravity at 9.80665 m/s2. A compact screw pump with ratchet handle is easy-to-use. The unit is also available as a deadweight gauge for accurate measurements and use as a comparison standard.
Low center of gravity
he HL tester is an easy-to-use and portable primary standard capable of offering laboratory accuracy in the field. The unit is designed to be self-contained with all necessary components stored under the cover. A screwpump pressure source on the tester model offers a convenient method to raise and lower pressure for rapid testing.
- Presure Range
100 to 22,500 kPa (10 to 3,000 psi)
to ±0.05% of Indicated Reading
- Available units
psi, kg/cm2, bar, kPa
- Interchangeable Weights
Models are available with dual piston/cylinder assemblies that utilize one weight set.
- Compact Design and Portability
The HydraLite is designed for use in the field and is completely self-contained within the cover of the unit.
- Includes Compact Screw Pump with Ratchet Handle
The tester models are supplied with a convenient screwpump as a pressure source. This pump has a ratchet feature that prevents the unit from depressurizing unexpectedly. The gauge model can be retrofitted with the pump as an accessory.
- Overhung Weight Carrier
Reduces side thrust and friction on the measuring piston and cylinder assembly, thus improving measurement accuracy
- Positive Over-pressure Protection
Prevents Piston Damage
- NIST Traceable
All units are supplied with certifications that are traceable to NIST.
