Brief introductionProduct introduction

YEJ-101The rectangular membrane box pressure gauge is suitable for measuring micro pressure and negative pressure of neutral and non explosive gases that do not corrode copper alloys, such as boiler ventilation equipment.

YEJ-101type rectangular capsule pressure gauge it is suitable for boiler ventilationequipment and other neutral and non corrosive to copper alloy、micro pressureand negative pressure of gas without explosion risk shall be measured.

YEJ-121The rectangular contact membrane box pressure gauge is suitable for measuring the micro pressure and negative pressure of neutral and non explosive gases that do not corrode copper alloys in boiler ventilation equipment. And it has dual two position adjustment(Double limit messaging)The function is to achieve positional adjustment or over limit alarm
