The new System 281 for the IQ Sensor Net - Universal monitor WTW DIQ/S 281-CR2 is a low-cost alternative to single point monitoring of pH / ORP, dissoved oxygen, turbidity or conductivity.
The WTW 281 Controller is a direct replacement for the IQSN 181 Controller
With the system 281, WTW offers a digital and cost-effective alternative to analog measuring points. Our IQ sensors (also as seawater version) are available for the parameters pH/redox, conductivity, oxygen or turbidity.
You will receive a cost-effective measuring point with proven WTW IQ Sensor Net technology. In addition to the power supply via a wide range power supply (100-240VAC) or via 24 V, 2 current outputs and 2 relays are also available.
Developed for wastewater, successfully applied in drinking water applications and the process industry for many years: The robust products of WTW are
made for many applications. Try it yourself!
Dual IQ/System 281, Universal monitor for the connection of 1 digital IQ sensor (pH/ORP, D.O., conductivity or turbidity), with 2 analog outputs (0/4-20 mA) and 2 relays, 100 ... 240 VAC
Similiar to the DIQ/S 281, but for 24 V AC/ DC voltage supply
