Backscatter Immersion Process Probe

Applications: • Crystallization control • Fermentation control • Cell culture & biomass monitoring Interface detection The Kemtrak backscatter immersion probe is designed to accurately measure low to extremely high turbidity directly in tanks and pipelines. The immersion probe has the same dimensions as industry standard 012 mm PG 13.5 pH sensors allowing a range of standard fittings and retractable probe holders to be used. The dual fiber optic design of the immersion probe provides high resolution at low turbidity with excellent linearity all the way up to extremely high turbidity when used with a Kemtrak NBP007 near-infrared backscatter photometer. A unique benefit of the Kemtrak backscatter immersion probe is that it does not go blind at high sample turbidity. Other probes will stop working at 4 000 NTU/FNU (<1 wt% solids) after which the signal will decrease resulting in an erroneous and misleading output. The output of the Kemtrak probe will continue to increase with sample concentration ensuring a reliable measurement. Immersion Bacscatter Probe Comparission The compact design of the immersion probe makes the instrument suitable for laboratory bench-top work to the most demanding commercial process installations. Standard probe design is in 316L stainless steel or Hastelloy C-22 with a robust scratch resistant sapphire window. The highly polished unbroken probe surface ensures freedom from fouling and suitability for sanitary applications. The fiber optic immersion probe has no electronics that will be damaged by high temperature process streams or sterilization cycles and is suitable for hazardous area use. Retractable probe holders can be used for automated cleaning and validation. All Kemtrak products are made from the highest quality materials and are designed to the most demanding specifications to ensure long life and the highest reliability. www.kemtrak.com Suspended solids concentration
