TEST PRESSURE GAUGES PRESSURE CONTROLS Test pressure gauges RIB850 They are used to calibrate and test industrial gauges or for precision measurements in the laboratory; they can be used for both liquid and gaseous fluids, except for those having a high viscosity or prone to crystallisation. Each gauges is supplied with a calibration certificate issued by our lab, indicatin the global error of the gauge and the references to the primary gauge use for the calibration.
