Universal monitor DIQ/S 181


The new system 181 – the digital and cost-efficient single parameter measuring point with proven IQ Sensor Net technology and matching fixed cable sensors

  • Low-cost alternative to analog measuring points
  • Matching digital IQ fixed cable sensors for pH/ORP, conductivity, O2 and turbidity
  • Stable, robust and proven measuring technology

With its system 181, WTW offers a digital and cost-effective alternative to analog measuring points. For the parameters pH/ORP, conductivity, oxygen or turbidity, we offer our new IQ fixed cable sensors.

You will receive a cost-effective measuring point with proven WTW technology. In addition to the power supply via a wide range power supply (100-240VAC) or via 24 V, you will also have 2 power outputs and 3 relays at your disposal.
