Ashcroft PHT-WS-100-01 Hydraulic Gauge Tester

Ashcroft PHT-WS-100-01 Hydraulic Gauge Tester is a portable deadweight-style calibrator that serves as a primary standard for calibrating hydraulic pressure gauges and related instruments in the field or on-site. It includes a weight set and a compact hydraulic source, aligning with Ashcroft's 1305D/1305DH portable deadweight testers that are designed for precise pressure generation and field calibrations. The 1305D family specifies a test range from approximately 15 psi up to 10,000 psi and uses SAE 20 automotive or machine oil, while the 1305DH variant is designed for phosphate- or glycol-based hydraulic fluids such as Skydrol 500B-4. The system typically ships with a complete set of weights stored with the tester and necessary ancillary components for assembly and operation, enabling accurate static pressure generation across multiple test points. Portable construction and included weight set make it suitable for calibrating gauges, transmitters, and transducers in industrial hydraulic systems.
