Description
Digital electro-chemical IQ sensors for dissolved oxygen, connectable to the IQ Sensor Net

TriOxmatic^® IQ: Reliable and proven digital electro-chemical 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 electro-chemical 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.

Models:
- TriOxmatic^® 700 IQ: Universal oxygen sensor for the measurement and regulation of oxygen input in wastewater treatment plants
- TriOxmatic^® 700 IQ SW: The sea water model is optimized for the use in special media such as desalination plants, seawater or brackish water, fish farming or high salt content. All wetted parts consist of titanium and plastic and are therefore extremely corrosion-resistant.
- TriOxmatic^® 701 IQ: Like TriOxmatic^® 700 IQ, but with faster response times
- TriOxmatic^® 702 IQ: Like TriOxmatic^® 700 IQ, but as a trace sensor (ppb area) suitable for pure or boiler feed water
Applications:
- Wastewater
- Drinking water
- Aquaculture
- Surface water
- Industry
