Automatic Dead Weight Tester
A deadweight tester is a calibration standard that uses the principle of a pressure balance to calibrate pressure measuring instruments. Deadweight testers use calibrated weights to apply known pressures to a device under test for a simple and cost-effective solution that covers a wide range of pressure calibrations. A key advantage of using a deadweight tester is that all of the hardware required to generate pressure and precisely control and measure it can be contained within the instrument. Deadweight testers are known for their best-in-class uncertainties, fast stabilization times, easy fine-adjustment, and a unique mounting post design that allows you to seal the device under test using only your fingers.
