2021 Good Quality Dissolved Oxygen Electrode - CS1668 Plastic Housing pH Sensor – Chunye Detail:
Complex environment
✬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, and is suitable for monitoring the flue gas desulfurization environment.
✬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.
