PH & REDOX MEASUREMENT
THE UNIQUE AND PRACTICAL DESIGN OF PHIX COMPACT ENABLES MEASUREMENT OF PH OR REDOX POTENTIAL FROM THE MEDIA IN WHICH IT IS SUBMERGED.
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 securing high repeatability.

LOGGING DATA TODAY IS NOT JUST PROCESSING DATA SUCH AS OXYGEN, PH OR LEVELS. WE MEASURE AND LOG DATA FROM RESERVOIRS, LAKES, RIVERS, STREAMS, CREEKS, GROUNDWATER, SURFACE WATER, HARBORS AND MANY OTHER PLACES TO HELP ADAPT AND IMPROVE OUR INFRA STRUCTURE.
Logging data far away from urban areas is handled by a battery powered datalogger, that gather information and send the information to a SCADA system, dedicated databases or even as e-mails when its suitable to do so.
Publicly placed dataloggers are vandal protected, and will send a warning when intruders act.
Sending data once a day will provide at battery life time of up to 5 years.
Information on ground water levels and early warning sewer systems in correlation with buildings nearby urban construction can save millions of Euros in damage.
