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.
