Anderson Negele turbidity monitors—particularly the ITM 51, ITM 4, and ITM 4DW—provide real time, high precision turbidity measurement for hygienic food, beverage, dairy, and brewing processes. Using advanced backscatter or four beam optical measurement technology, these sensors eliminate the need for manual sampling or sight glass inspection by monitoring turbidity directly inline, enabling automated product differentiation, phase transitions, and quality control.

1.) Real‑Time, Accurate Inline Measurement

• ITM‑51 backscatter sensor measures turbidity from 200–300,000 NTU with ±3–5% accuracy. 
• ITM‑4 four‑beam sensor compensates for contamination, aging, and optical drift automatically. 
• Readings are color‑independent (infrared 860 nm), ensuring consistent, reliable data regardless of product color. 

2.) Hygienic, Robust Construction

• Wetted parts made of 316L stainless steel, PEEK or PPSU optics, and sapphire glass windows for maximum durability. 
• Designed to meet 3‑A, EHEDG, and FDA hygienic requirements. 
• CIP/SIP capable up to 130–140°C for 120 minutes, depending on model. 

3) Automation & Process Efficiency

• Enables precise phase separation between product, water, and cleaning solutions—reducing product loss and saving water, chemicals, and time.
• Inline measurement eliminates laboratory sampling and increases process consistency.
   Example: ITM‑51 studies show reduced raw material loss, lower wastewater treatment costs, and up to 3,000 L water savings per CIP cycle. 

4.) Flexible Installation & Integration

• Available with Tri‑Clamp, CLEANadapt, Varivent, and other sanitary connections for pipelines as small as DN25. 
• Outputs include 4–20 mA, IO‑Link, switching outputs, and selectable units (NTU, EBC, %TU, %solids). 
• Fast response (<1 second) enables immediate process adjustments.
