Anderson Negele - Turbidity Sensor ITM-4

  • 4-beam Alternating Light Method
  • Measuring Range: 0…5000 NTU (0…1250 EBC)
  • Operating Pressure Max 10 bar
  • Approvals: FDA; 3-A

Product description

The Anderson-Negele ITM-4 Meter is the ideal product for low turbid media, with the ability to read turbidity levels between  0-5000 NTU (0-1250 EBC), this turbidity sensor is designed to be highly accurate and lends itself to the brewing & beverage industry, water processing, dairy processing, pharmaceutical applications as well as many other industries that require an accurate quality control of their fluids and waste products.


The ITM-4 can be scaled to read as low as 0-5 NTU (0-1 EBC) for the lowest of turbid media and being a compact product needing no evaluation unit, installation is quick, non-intrusive and simple. The ITM-4 can begin optimising your system and saving you on waste products and line changes from the day that it is installed from, paying for itself within a surprising period of time and saving the customer on wastage costs effectively.


Conforming to FDA standards, the ITM-4 turbidity sensor is hygienic by design. Utilising PEEK for the optical block, sapphire crystal for the glass panes on the sensors and having fittings that are completely stainless steel in construction, the ITM-4 is versatile and can be used on pipes as small as DN 25. With use of the Tri-Clamp and hygienic thread connection, we can offer the ITM-4 with 3A Certification as well for pharmaceutical applications.


Utilising the “4 Beam Alternating Light” principal to measure, the ITM-4 is able to largely cancel out disturbing media such as air bubbles and the occurrence of solids in an application, due to the evaluation of multiple measurement cycles of transmitted and 90° scattered light. This differentiates the ITM-4 from its competitors that often struggle to deal with the sporadic occurrence of solids and bubbles in processes causing loss on downtime and potential waste.


Application Examples:


  • Control of brewing processes.
  • Fresh water control in the beverage industry.
  • Water and waste water control in dairies.
  • CIP/SIP Systems.
  • Quality control.
  • Separator monitoring.
