TurbiTechw² D-ISO Sensor
It’s an extremely sensitive sensor can detect changes in Turbidity of less than 0.01 FTU. It’s global standard of light scatter technique makes the sensor sensitive to a wider range of particle sizes.
The TurbiTechw² D-ISO Sensor is now SPAN (Suruhanjaya Perkhidmatan Air Negara) certified!
The sensor requires very little maintenance, with no 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 provides an extremely easy, repeatable method of checking the performance of the sensor, without the cost and inherent errors associated with chemical standards.
