Inline sulphuric acid concentration measurement

The concentration of sulphuric acid (H2SO4) is calculated from conductivity and temperature measurements. The measurement provides sulphuric acid concentration as % or g/l without on site development work. We also provide oleum (SO3) measurements for sulphuric acid plants and users.

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.
