Turbidity Sensors: ITM-4DW

Best in class Turbidity measurement for very low turbidities in process and drinking water applications, in pipes from DN25

Specified Advantages & Usage

  • Turbidity measurement in the range of 0…5000 NTU or 0…1250 EBC
  • Cost efficient sensor, optimised for process and drinking water (Optik device made of PPSU)
  • Accurate turbidity measurement also for media with low turbidity
  • Glass-free sapphire optics with pollution compensation
  • For increased efficiency in production processes such as separator automation, lauter tun control and filter monitoring
  • ITM-4DW is not intended for applications with liquid food contact. For the application with drinking water a declaration of conformity for the PPSU material is available

Application Examples

  • Fresh water monitoring in the beverage industry
  • Water/wastewater monitoring, e.g. in dairies
  • Coolant circuit monitoring

Designed for process- and drinking water applications

The new turbidity meter ITM-4DW is especially designed for process- and drinking water applications. Therefore we changed the plastic components and now using PPSU (Polyphenylensulfon).

Metrological the ITM-4DW is identical with the ITM-4.

The combination of transmitted light measurement and 90°- reflected light measurement allows the detection of low (fresh water) to mid (waste water) turbidities. Due to these facts combining the two techniques the ITM-4DW has the benefits that pollution of the optics will be almost ignored.

The ITM-4DW is not suitable for food contacting usage. For the use in drinking water applications a declaration of conformity for PPSU is available.
