SentroProbe DR LS

For DR measurement in NIR range

The SentroProbe DR LS NIR is a smart probe for measuring diffuse reflectance in the near infrared range. Two redundant light sources are used to directly illuminate the sample, which results in a better signal-to-noise ratio at a 5 mm spot size. Installation expenses are affordable even for lengths of up to 50 metres because the integrated illumination is connected to the SentroPAT FO using single core optical fibres.

When the probe is used in conjunction with the SentroPAT FO and set up with SentroSuite GMP, it is a complete solution that offers insightful process information, from product development to routine operation. High reliability is ensured with a dual-light source, and the optimised diode array, which takes several spectra every second, is perfect for measuring fast moving products.
