Measure it, generate it, or define it
Digital test gauges to measure pressure, hand pumps to generate it, and dead weight testers to define it, for calibration and field verification from vacuum to 2500 bar. Someone on the end of the phone who has used them.

Tell us the pressure, the media and what you are checking. We will tell you what fits.
High-accuracy digital gauges for pressure and vacuum, with fast update, min and max capture and data logging on selected models.
Hand pumps to generate, adjust and hold pneumatic or hydraulic pressure for calibration and test, with a test port for the reference gauge.
Hydraulic piston gauges that define pressure from mass and area rather than measure it: the reference the rest of the pressure kit is checked against.
Nothing matches that filter. Choose All to see all three sub-categories.
Buying an instrument from us comes with the part that is harder to buy: knowing whether it is the right one, and knowing what it is traceable to.
Advice on accuracy, stability and uncertainty budgets, and on which reference is good enough for what you are checking.
Vacuum to 2500 bar, gauge or absolute, in air, water or oil, across gauges, pumps and dead weight testers.
The right thread, the right medium and level compensation sorted before the order, so the kit fits together on day one.
One year warranty, with optional UKAS calibration arranged at the time of order and recalibration when it falls due.
Gauge pressure is measured against ambient, absolute against a vacuum, and differential between two ports. Choose the one your process uses as its reference; a gauge-referenced instrument on an absolute process reads wrong by one atmosphere and looks fine.
As a rule, four to ten times better than the tolerance you are checking. A 0.5 percent process gauge wants a 0.05 percent reference. For calibration work, look at the stability over a year and the temperature effect across your range as well as the headline figure.
Pneumatic for vacuum and low pressure air, hydraulic for anything higher. Check the media the instrument under test can take, oil or water, and the fine-adjust resolution you need to sit on a calibration point.
When the instrument under test is itself a reference, or when you need the uncertainty to come from mass and area rather than from a sensor that drifts. A dead weight tester defines the pressure; a calibrator measures it. Most workshops use a calibrator day to day and a dead weight tester to check the calibrator.
