The equipment is self-contained and portable, so it may be used in lecture theatre demonstrations or as a master calibrator for the laboratory.
Deadweight testers are the basic primary standard used worldwide for the accurate calibration of pressure gauges, pressure transducers etc. The instrument combines a low and high-pressure range provided by two pistons of different effective area.
Calibration is accurate to within ±0.025% of reading. A laboratory calibration certificate is supplied for each piston together with a traceable certificate of overall accuracy.

Ltekonline are the manufacturers of Precision Pressure Gauge Calibrator used to demonstrate engineering principles in Engineering Colleges, Engineering Schools and Fluid Mechanics Lab Equipment for Engineering Teaching Lab in Universities
