A Product by WTW GmbH

The pHotoFlex® Turb is analogous to the pHotoFlex® pH, but includes an infrared (IR) light source for nephelometric turbidity measurement (90°), according to the requirements of DIN 27027/ISO 7027. Its precision is comparable to laboratory instruments for turbidity measurement.
