This series Diaphragm-seal Pressure Gauge is used to measure the pressure of media which are strongly corrosive, extremely hot, highly viscous, easy to crystallize, or have solid suspended matters.

To avoid the measured media from entering the general service pressure gauge directly and prevent the sludge from gathering at the place that is not easy to clean, a diaphragm isolator must be used together with the general service pressure gauge to form a systematic diaphragm pressure gauge

It applied to Chemical Industry，Chemical Fiber，Synthetic Fiber industry， petroleum，dyestuff Industry，alkaline industry etc.

Working Environment: no corrosive gas.
