The sensor requires very little maintenance, with no special tools or training required. Calibration can be carried out against either a wet turbidity standard or using the dry calibration reference cell that is supplied with every sensor. The reference cell provide an extremely easy, repeatable method of checking the performance of the sensor without the cost and inherent errors associated with chemical standards
