SI Analytics Armature

The development and production of these high-quality armatures and its control systems is based on our experience originating from more then 70 years within the area of liquid analysis. Thanks to the constant active contact to our customers we are aware that basically every application has its own requirements. The reliable measuring of pH, redox, conductivity and D.O. values up to temperature within the process requires individual solutions. This affects all industrial branches, whether within the water treatment, food industry, biotechnology or chemical and pharmaceutical productions.
