DIQ/S 181 - Universal Monitor

Digital single parameter measuring location for O2, pH/ORP, conductivity or turbidity
The system 181 – the digital and cost-efficient single parameter measuring point with proven IQ SENSOR NET technology and matching fixed cable sensors:

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.
