Our comparison testers
Can you test and calibrate different instruments with one instrument? You can with a comparison tester. This is a very simple and robust instrument used to test or calibrate instrumentation against a reference standard. These instruments are equipped with a precision spindle pump that can generate pressures as high as 700, 1400, 2500, 4000 and 7000 bar. The amount of fluid displaced per stroke is sufficient to test most instruments at any range without the need for a pre-pressure pump.
