Home » TurbiTechw² D-ISO Sensor
Building on the success of the TurbiTechw² LR sensor and by continually striving to improve and expand our product range Partech is proud to introduce the new TurbiTechw² D-ISO sensor. The D-ISO is a natural evolution in terms of development and offers our customers an improved user experience in all areas.
The TurbiTechw² D-ISO was developed using valuable feedback from existing customers and incorporates that feedback into its use and function.
Uses 40 years of sensor design to produce a new sensor that captures stray light to ensure a stable zero point.
A new automatic self cleaning mechanism that prevents the build up of fouling in and around the chamber making this the benchmark for low range turbidity.
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 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.
