Features Specifications

  • These instruments have been designed for laboratories, instrument testing or recalibration facilities and in other applications where accuracy and repeatability are of primary importance. Whenever is requested the conformity to safety normative EN 837-1 and ANSI B40. is possible to use the models NFC: these instruments have a solid separating wall in stainless steel, placed between the dial and the elastic element and an integral blow out back that is released from the case whenever a pressure is created inside the case, due to leaks or accidental ruptures of the elastic element. They can be used with fluids or gasses that do not have high viscosity and do not crystallize. The wetted parts in beryllium copper of model NFC permits higher accuracy.

    Each instrument is supplied with a calibration certificate that guarantee the traceability to the National and International master primary instruments. Upon request we can supply the calibration certificate issued by an Internationally recognized Accredia laboratory.
