IQ Sensor Net System WTW IQ Sensor Net DIQ/S 281-CR2 Controller

Overview Solutions Documentation & Tools
Overview

Simple, Digital, and Modern Measurement of pH, ORP, Dissolved Oxygen, Turbidity, or Conductivity

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

 

Product Features
  • Proven and reliable IQ Sensor Net technology
  • 100 % IQ Sensor Net look & feel
  • 2 mA for main and secondary parameter
  • 2 relays for alarm for main and secondary value
  • You can easily upgrade to DIQ/S 282/284, since IQ sensors can be retained
  • Free software updates with new features

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.

Application Examples

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!
