Engineered specifically for aquaculture applications, but at home in any Modbus system, the optical dissolved oxygen (ODO) sensor can be used to ensure adequate oxygen levels for your livestock or for improved energy efficiency. With YSI’s ODO RTU (Remote Terminal Unit), you’ll benefit from reduced costs, less maintenance, and better data.
ODO RTU utilizes the most advanced DO technology and can be connected anywhere without the need for special connectors. Additional inputs for barometric pressure and salinity are used to accurately calculate the DO% and mg/L. ODO RTU is also available with built-in conductivity measurement to automatically compensate for salinity.

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.
