Our hydraulics dead weight testers are available in standard, high performance, differential and automatic versions.

Differentials dead weight testers BDH3

The BDH3 range of differential dead weights (hydraulic) is a reference for calibration !

Easy to use and robust, our range extends up to 1200 bar.

These dead weights have built-in motorization to optimize measurements. They have good results in terms of precision and good long-term stability.
Each dead weight consists of a pressure bench, two piston/cylinder assemblies and two sets of weights. The pressure balance comes with its set of weights calibrated with the gravitation you want.

High performance dead weight testers BH2

The BH2 (hydraulic) range has great assets to seduce you !

This range is simple to operate, robust, has good results in terms of precision and has the advantage of being scalable. In fact, you can later integrate several options: such as the motorization/visualization (option OP0004), the calculator with its sensors and the motorization/visualization (option OP0301). This range of DWT can therefore evolve according to your budgets and your needs.

Each DWT consists of a pressure bench, a piston/cylinder assembly and a set of weights. They exist in single or double piston for pressures of 300 bar, 600 bar and 1200 bar.
The DWT is delivered with its set of weight calibrated with the gravitation you want and the desired unit of measurement.
 

Automatics dead weight testers BH4

Our automatic dead weight testers models BH4 (pneumatic) are very high performance devices, this range is ideal for regular or intensive calibrations requiring high precision. It is popular with calibration laboratories.

Model BH4 incorporate a calculator. This automaton allows: to motorize the set of weights, to have a dynamic visualization of the position of the piston, to automatically display the pressure generated by the scale according to the temperature, the atmospheric pressure and the hygrometry.

This automaton assists the operator in the calibration process, it indicates the measurement points to be carried out according to the criteria requested. It indicates the weights to be applied, and indicates any deviations observed or handling errors.

The calculator allows total traceability because it records the measurement results and allows the transfer of data to a computer for the edition of instrument control reports. You will also have the possibility to change the unit of measurement while keeping the same set of weights
 

High pressure dead weight tester BH5

This dead weight tester model BH5-10000B is a revolution for laboratories. It is a good alternative solution to the current reference means in place.


This primary standard is capable of generating 10000 bar with only 50 kg of mass. Simple to implement, the dead weight takes up little space and its set of weights is a real comfort of handling. Its development required several years of research, its manufacture is French, and the results obtained have been approved by national laboratories.
