PG.RI.100ST (China)


Brannan (PG.BR.ST) and RITherm (PG.RI.ST) Series Gauges are complete  stainless steel construction gauges and are resistant to corrosion. The complete stainless steel pressure gauges are constructed with solid 304 SS case and bezel. The connection and bourdon tubes of the gauges are made of 316 SS which makes the gauge resistant to aggressive media and environments. The gauges are equipped with a safety glass lense for additional protection. 

The glycerin filling enhances the gauge’s lifetime by keeping the movement lubricated at all times and reduces the effects of vibration, pulsation and shock. Yet, the gauges are designed with a measuring system with an accuracy of 1.0% to give the users a smaller window for error.
