Product Overview

The TurbiGuard AD 40 is an in-line measuring device for medium to high turbidity, suitable for continuous process monitoring. It uses a highly reliable LED-based absorption measuring system. This modern process measuring device is designed for seamless integration into existing process lines and offers a very short reaction time for real-time monitoring. Its fully optimised, seal-less design with sapphire windows ensures extremely low maintenance and high reliability, contributing to low Total Cost of Ownership (TCO) and a fast Return on Investment (ROI).

Key Benefits

• Real-Time Monitoring with a very short reaction time.
• Extremely Low Maintenance due to the seal-less design.
• Hygienic Design compliant with EHEDG standards and Regulation (EC) No 1935/2004 for food contact materials.
• High Measuring Range with linearised factory calibration in EBC or NTU.
• Process Control helps to avoid faulty batches and secures end-product quality by measuring turbidity and recognising deviations early.
• Low TCO (Total Cost of Ownership) and fast ROI (Return on Investment).

Applications

• Turbidity measurement or monitoring in beverages such as beer and fruit juices.
• Control of centrifuges, separators, whirlpools, etc.
• Filter performance and filter breakthrough monitoring.
• Determination of solids concentration.
• Yeast pitching and yeast dosing.
