Dead Weight Pressure Gauge Tester
Product Code : EL-TOML-11031
Quick answer: The dead weight pressure gauge tester is used to check and calibrate pressure gauges by comparing their reading with a known pressure produced by calibrated weights on an oil-filled piston system. It covers gauges up to 25 kg/cm², with zinc-iron weights and a nickel-chrome plated body. Lab Exports manufactures it in Delhi for engineering colleges, polytechnics and TVET institutes.

How the dead weight tester is used
A dead weight tester produces a known pressure from first principles. Weights of known mass are loaded on a piston of known area that floats on oil, and the pressure in the oil is p = m x g / A. Because this depends only on mass and area, the tester serves as a reference against which ordinary gauges are checked.
The gauge under test is connected to the same oil circuit. For each weight added, the true pressure is compared with the gauge reading, and the difference is the gauge error. Plotting error against pressure, for loading and unloading, shows the accuracy and hysteresis of a Bourdon tube gauge and teaches the calibration practice used in industry.
- Fit the gauge under test to the tester and fill the system with oil, removing any air.
- Place the first calibrated weight on the piston.
- Raise the pressure until the weights float, then spin them gently to reduce friction.
- Record the gauge reading against the calculated pressure.
- Add weights step by step up to the range, then unload in steps and record again.
