YQHB (N) All Stainless Steel Safety Pressure Gauge
About YQHB (N) All Stainless Steel Safety Pressure Gauge
HollySys YQHB (N) All Stainless Steel Safety Pressure Gauge designed for use in harsh and corrosive environments, capable of measuring non-viscous, non-crystallizing, and slightly corrosive gas and liquid media. A safety disc is incorporated into the casing to safeguard the observation surface. Additionally, the rear is equipped with a pressure relief back cover to mitigate internal pressure resulting from the rupture of overloaded elastic elements, thereby enhancing the safety of personnel and equipment. This product is primarily utilized in industries such as petroleum, chemical, metallurgy, power generation, food, pharmaceuticals, environmental protection, machinery, and shipbuilding.
