Pressure Gauges
SJ Gauge offers a complete range of pressure gauges, including general pressure gauges and low pressure gauges, for a wide variety of industrial equipment and pressure monitoring applications. General pressure gauges are designed for standard pressure measurement, while low pressure gauges are ideal for low-pressure, differential pressure, and slight pressure variation monitoring.
To meet different operating requirements, material options include 304 stainless steel, 316 stainless steel, 316L stainless steel, and copper alloy. Connection options are available in PT, NPT, and BSP threads, with bottom mount and back mount configurations to suit various equipment and piping layouts. Based on pressure range, media characteristics, installation method, and operating environment, SJ Gauge also provides product recommendations and customized solutions to help customers build more stable and reliable pressure measurement systems.
