Description

Any laboratory needs to verify periodically the calibrations of their electronic measuring systems, in order to produce reliable and accurate results. Equipment for calibrating force, displacement, volume change and pressure measuring devices.

Force measurement 

For calibration of force measuring devices we propose the following load cells fitted with digital readout unit, supplied complete with ACCREDIA calibration certificate according to EN ISO 376.

Pressure measurement 

Pressure calibrations are performed with a digital pressure gauge, supplied complete with ACCREDIA calibration certificate.

Volume change 

Calibration of the volume change apparatus can be simply performed by weighing the water coming out of the device, using any digital balance with 0.01 g resolution,


Displacment Measurement 

Calibration of displacement measuring devices can be performed with either the analogue or digital micrometer 25 and 50 mm travel respectively, 0.001 mm resolution. They are both available, optionally, with a traceable calibration certificate 25 mm and ACCREDIA certificate 50 mm 

Local strain measurement 

The calibration is performed with a special device that can also be used for standard linear displacement transducers with up to 50 mm travel.
