WQYT-X Gas Expansion Capillary Thermometer is a kind of analog pointer thermometer to measure temperature by air pressure. With all stainless steel construction and wetted part, it can measure high temperature measurement up to 650℃, suitable for corrosive environment in chemical industrial, processing, machinery, piping, building construction and various industries. Liquid fillable for extreme vibration application is available. WQYT-X Gas Expansion Capillary Thermometer is widely used in the measurement and control of temperature in the production process of petroleum, chemical, electric power, printing and dyeing industries. It features strong reliability, good stability and long service life, especially the miniaturization and simplification of the temperature package, which makes it more widely applicable.
