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.

The sea water 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 a faster response time or for the measurement of trace oxygen.
