Ashcroft Pressure Gauge Comparators

Field-portable pressure generation and test systems are ±0.1% accurate

Hydraulic two-stage pressure gauge comparator has a built-in shuttle valve that allows for rapid pressure increases at low pressures. A single carrying case holds the pump as well as the test gauge provided, a six-inch test gauge, accurate to ±0.1% full-scale. Test gauge provided has temperature compensation which maintains the ±0.1% full-scale accuracy over an operating temperature range of -25 to 125°F. Operating media is standard SAE 20 weight automative/machine oil.
