When is "close" ever accurate enough? With this in mind, the engineers at Dresser Instrument have improved the accuracy of the famous Heise® Pressure Master (PM) digital indicator. The PM now measures pressure and temperature to 0.025%. With the new 0.025% accuracy, the Pressure Master is perfect to calibrate 0.1% devices where a 4:1 calibration ration is required.

The rest of the Pressure Master remains its reliable, versatile self. It is available in over 200 standard pressure ranges from 0.25 in. H2O through 10,000 psi. Gauge, absolute, compound and differential pressure types are offered, as well as vacuum, plus the availability of many ranges in both isolated and non-isolated configurations.

PM indicators are ideal tools for use in most major pressure measurement applications like test stands, as in-field calibration and test standards, and for general metrology lab activity.
