Model DWT1305 Deadweight Testers are dual range, precision built hydraulic instruments for testing, setting, calibrating or repairing pressure measuring devices. Each instrument is self-contained and comes complete with tools and metal carrying case. With the optional "-CAL-3" calibration, the DWT1305 can by a primary standard with 0.1% accuracy of the pressure produced. Each unit is adjusted for standard gravity conditions, all weights are labeled and an NIST traceable certification is supplied.
SPECIFICATIONS Accuracy: 0.1% of produced pressure Operating Pressure: 15 psi to 10,000 psi max. (100 kPa to 70,000 kPa) Body Material: Aluminum Alloy Piston and Cylinder Material: Stainless Steel Weights: Nonmagnetic die-cast zinc alloy, NBS traceable Operating Fluid: SAE 20 Automotive or Machine Oil O-Rings: Standard Buna-N Reservoir Volume: Approximately 1.5 pints (0.7 liter)
