Our hydraulic range goes up to 10000 bar. All our devices are designed and manufactured in France. You will find the ideal standard or tailor-made solution among our pressure standards.
How to choose between a dead weight tester or a comparison bench ?

The hydraulics dead weight testers are intended for testing, adjusting and calibrating mechanical or electronic relative pressure measuring instruments (pressure gauge, pressure sensors or transmitters or pressure switches, pressure standard) by comparison with a set of weights. They can be either a primary standard for calibration laboratories or a reference instrument in industrial settings.
They consist of a pressure generator, a piston/cylinder unit, a set of identified masses. Its principle is easy, P=F/S. it consists of generating pressure by applying weights to a piston/cylinder assembly. The pressure obtained is almost immediate and allows the instrument to be calibrated is compared to the pressure values generated by the dead weight tester.
Our reference have very high long-term stability and have very little drift. It is the most accurate calibration device thanks to its low measurement uncertainty. Our dead weight testers are scalable and can integrate the motorization of the weights, the addition of sensors and a calculator etc..

The hydraulics comparison test pumps are intended for testing, adjusting and calibrating pressure measurement instruments (pressure gauges, sensors or pressure transmitters or pressure switches) by comparison with another standard instrument. These calibration benches are light and easy to transport; they are ideal for on-site interventions in an industrial environment but also in calibration laboratories.
They are equipped with a tank with visible level, connected to a set of variable volumes. The capstan allows you to generate pressure by pushing the fluid through the variable volumes towards the pressure fittings provided to receive your reference instrument and the instrument to be calibrated. Our comparison test pumps are robust and easy to use and have a very high long-term stability. They have the possibility of evolving into dead weight testers by simply adding a kit comprising: a piston/cylinder and a set of weights.
Many accessories can complete it such as the reservoir pump which can be coupled to the hydraulic bench in order to increase the volume of fluid, a micro-valve to refine the measurements, a calibration ramp for pressure gauges, a protective cover etc...
