EXplore 171

NIR backscattering sensor in compact design

EXplore 171 is a NIR turbidity sensor for monitoring production processes in the food industry, e.g. in dairies, as well as in many areas of other process applications with medium and high turbidity. The robust and compact design in stainless steel housing and the wear-free sapphire lens make the EXplore 171 a reliable back scattering sensor with integrated amplifier. The measured values are output via the standard interface of 4...20 mA.
