YQF-100 YQF-150 series stainless steel safety-type pressure gauge pressure gauge according to the type of corporate security standards. Products for harsh and corrosive environment. Table is designed with safety partitions. Back cover with relief and pressure relief hole to release the elastic component breakdown due to overload and the internal pressure, increased personnel and facilities security. 

 All stainless steel safe has a liquid-filled pressure gauge at the top of plug and an internal compensation diaphragm, filling in the scene. Type liquid-filled pressure gauge with seismic safety and damping properties, can prevent vibration of the internal gauge damage, but can also lubricate internal components to reduce corrosion. 

 This series of instruments are widely used in food, pharmaceutical, oil refining, chemical, offshore oil platforms, drilling, shipbuilding and other industries.

 Third, pay attention to: 

 When glycerol or silicone oil and grease chlorine, nitric acid, nitrogen oxides and other strong oxidants mixture, spontaneous chemical reaction will have a fire or explosion resulting in equipment damage, casualties may be. When the pressure gauge used for these occasions are not filled with glycerin or silicone oil grease, please contact the manufacturer, filling in the correct oil-filled.
