Hydrofluoric acid (HF) measurements

The concentration of hydrofluoric acid (HF) is calculated from conductivity and temperature readings. Valmet provides ready made recipes for measuring the hydrofluoric acid concentration or the amount of water in anhydrous hydrofluoric acid. All equipment is delivered readily calibrated so there is no need for hazardous sampling on site. All you have to do is install the sensor and power up the measurement. Valmet concentration measurement is superior in high purity hydrofluoric acid measurements because Valmet conductivity sensor can accurately measure very low conductivity of pure hydrofluoric acid.
