Type T Pressure Comparator (System F)

Brand: Crystal Pressure

Our high-pressure, hydraulic pressure comparators are portable, self-contained, hydraulic pressure generators for calibrating pressure gauges, transmitters, sensors, and safety valves.

They are much faster than deadweight testers and most automated pressure controllers; and it’s so quick and easy to use, it’s ideal for calibrating those low cost gauges that are often overlooked for ISO9000 compliance.

Each pump is available on its own, or in one of our complete ready-to-use pump systems.

Type T hydraulic comparator (System F) is a self-contained high volume pressure source capable of producing pressure up to 15 000 psi.

It is ideal for testing gauges and setting hydraulic relief valves and pressure switches. Multiple models are available for hydraulic oil, water, or both.
