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.
Universal monitor DIQ/S 281-CR2. The new system 281 – the digital and cost-efficient single parameter measuring point with proven IQ Sensor Net technology and IQ sensors for the standard parameters. Low-cost alternative to analog measuring points
The System 281 combines the known performance of analog products with the advantages of the digital IQ Sensor Net:
• 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
• Matching digital IQ sensors for pH/ORP, conductivity, O2 and turbidity
• Stable, robust and proven measuring technology
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.
