ITM-4DW

Turbidity Sensors, Process Analytics

The ITM-4DW Four-beam Turbidity Sensor detects and signals any variation in turbidity in real time, thanks to its very high sensitivity starting from 0 NTU and a response time of <1 sec. This offers significant advantages in many applications like process monitoring, control and automation. The ITM-4DW is technically identical to the ITM-4, but a more cost efficient sensor, optimised for process and drinking water (Optics device made of PPSU/FDA-approved)

  • Colour-independent measurement with 90° and 180° light
  • Superior accuracy starting from 0 NTU, resolution from 0.1%, repeatability from <2%
  • Monitors different products in one line
  • Cost-efficient solution with optics made of PPSA (FDA-approved)
  • Switching and analog (4-20mA) outputs with 4 selectable ranges
  • Durable precision even with solids or air bubbles
