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.
Your benefits
- The system offers outstanding stability as a results of internal referencing directly at the probe window
- Even when the pharmaceutical product adheres to the sapphire, visibility is maximised thanks to the process window's heating
- The two pre-adjusted light sources are simple for non-expert users to swap out
- The small size and various shaft lengths make mechanical integration simple
- Bulbs are recognised and identified automatically after a manual replacement
- A heating element can be set up on the product-contact surface. This extra feature improves the capacity for self-cleaning
