The Ralston Quick-test™ hose is unique because it can be attached and detached without a wrench or thread sealant while maintaining a working pressure of 6900 psi (475 bar). Quick-test™ hoses are small in diameter, flexible and low in volume. These hoses provide an ideal way of transmitting pressure during a vacuum or pressure calibration. A wide variety of adaptors provide a connection for most calibration applications.
Calibration tests are only as good as the pressure reference. When your pressure calibrator helps you complete work and follow standard operating procedures, it does even more than provide accuracy. Intrinsically safe with 0.1% of reading accuracy, the Ralston FieldLab Digital Pressure Calibrator is a digital pressure calibrator that works the way you do.
Ralston Instruments' Test Pumps are rugged and portable. Field tested calibration solutions with standard Quick-test adapters which make connecting to pressure references and the device being calibrated a snap.
