Nitric acid (HNO3) concentration measurements

The concentration of Nitric acid (HNO₃) is calculated by measuring the conductivity and temperature of the acid. Valmet offers readymade concentration measurement recipes for various Nitric acid concentrations. The sensors are readily calibrated and the cell constant is stored in the sensor memory. All you have to do is install the sensor in the process pipe and power up the measurement.

Valmet Concentration measurement is maintenance free and accurate thanks to 4 electrode technology. The sensors are designed to withstand rapid temperature changes have a long lifetime even in the most demanding applications.
