PHDS212 Digital pH Sensor Designed for viscous fluids, protein environment, silicate, chromate, cyanide, NaOH, seawater, brine, petrochemical, natural gas liquids, high-pressure environment.

Easy to connect to PLC, DCS, industrial control computers, general purpose controllers, paperless recording instruments or touch screens and other third party devices.


Double salt bridge design, double layer seepage interface, resistant to medium reverse seepage.
The ceramic hole parameter electrode seeps out of the interface, which is not easy to be blocked.
High-strength glass bulb design, the glass appearance is stronger.
Large sensing bulbs increase the ability to sense hydrogen ions, and perform well in complex environment.
The electrode material PP has high impact resistance, mechanical strength and toughness, resistance to a variety of organic solvents and acid and alkali corrosion.
Digital sensor with strong anti-interference ability, high stability and long transmission distance.
