TriOxmatic® 702 IQ
Universal oxygen for measuring and controlling oxygen input in the biological sewage treatment process in wastewater treatment plants.
Digital electro-chemical IQ sensors for dissolved oxygen, connectable to the IQ SENSOR NET TriOxmatic® IQ: Reliable and proven digital electrochemical oxygen sensors with 3 electrode system (ECDO) for precise and accurate measurements:
•Low investment costs
•No running in, no long-term drift - stable from the beginning to the end
•Self-diagnosis system SensReg/SensLeck by means of 3 electrode system
The electrochemical sensors are known for their high accuracy - from the beginning. Their Teflon membrane makes them extremely insensitive to biological deposits. Therefore, in most cases, you will not need an additional cleaning unit.
Also, the membrane - just like the electrolyte consumption - is monitored continuously. Our self-diagnosis system SensLeck and SensReg show occurring errors automatically. The seawater model is optimized for the use in special media: All wetted parts consist of titanium and plastic and are therefore extremely corrosion-resistant. Furthermore, if you want, you will find a sensor with faster response time or for the measurement of trace oxygen.| Model | TriOxmatic®700 IQ | TriOxmatic®700 IQ SW* | TriOxmatic®701 IQ | TriOxmatic®702 IQ |
