Hydraulic and Gauge Deadweight Tester Presure Range 100 to 22,500 kPa (10 to 3,000 psi) Accuracy to ±0.05% of Indicated Reading 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. 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. The 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. ISO 9001 Manufacturer Specification Sheet SS-Model HL

FEATURES Two accuracies available Overhung weight carriers These instruments are available in ±0.100% and ±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. Site corrections are the user’s responsibility and the unit will not perform as specified without them.The testers are manufactured to International Standard Gravity and a local gravity site correction is easily performed with a ratio correction to the output. Another feature of HL...

General Process Information for Calibrated Parts • Include serial number, accuracy, gravity, and model number of deadweight tester when ordering weight sets or calibrated parts. • Masses for weights ordered seperately, including tolerance, must be supplied by customer; unless combined with tester on same order. • Calibrated parts may be made to archival data if requested on the purchase order. • Calibrated parts are certified for physical dimension only (mass or area) and not for accuracy unless ordered with a new tester or the tester is returned for proper calibration of parts....
