Specification

Low pressure gauges 312M/322M are produced according to standard EN837-3. Mainly used for pressure measuring of liquids, vapour and gases, that do not have corrosive effect on copper alloys.

Low pressure gauges are designed for very low pressure measurements up to 400Pa. Used primary in gas distribution. Environment temperature -40 up to 60°C,medium temperature Tmax 60°C. Low pressure gauges are equipped with regulatory bolt for exact reset, when it is required to set zero value before each installation.

Other design options on request special scale design, connection thread, glycerine or silicon damping, front/back flange, etc.
