Pressure Gauges

CEJN's range comprises of both bottom and panel mounted pressure gauges in models up to 5500bar (550 MPa). All models are glycerine filled for improved performance and long life. The gauges are made of stainless steel, which means they can be used in dirty and rugged environments. The pressure gauges can be connected by means of a porting block.
