pHix® Compact Transmitter

The unique design of pHix Compact eliminates high impedance electrode connections and use of special hardware for mounting, and, with the large surface of the pHix Compact reference junction, the electrode is less sensitive to pollution.

All known issues – such as corrosion, moisture and oxidation due to high impedance – are practically eliminated with this construction.

This is one of the most user friendly pH transmitters on the market. The buffer adjustment of the pHix Compact is very easy to perform, which secures high repeatability.

In addition to measurements in wastewater applications, due to the new rough materials and long-term stability of the sensor and electrode, the pHix® Compact v.3 is now very suitable for pH measurement in waste & drinking water applications, marine applications, process applications, industry applications and aquaculture applications.
