Universal monitor DIQ/S 281, SKU: 472103, DIQ/S 281-CR2- Controller for 1 IQ Sensor, 230 V - WTW Germany

Universal monitor DIQ/S 281. 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
• Versions with analog outputs, Modbus RTU and HART available
• 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
• Stable, robust and proven measuring technology

Made for many applications:

Once developed for wastewater the IQ Sensor Net is also successfully applied in drinking water applications and the process industry for many years. Try it yourself! Some examples:

• With SensoLyt® 700 IQ for different pH ranges in drinking water
  
• With VisoTurb® 700 IQ, the turbidity sensor with ultrasonic cleaning in the wwtp outlet
• With the calibration free dissolved oxygen sensor FDO® 700 IQ in the aeration basin
  
• With TetraCon® 700 IQ, the 4 electrode conductivity cell in the process industry
  
• With the suspended solids sensor ViSolid® 700 IQ with ultrasonic cleaning in the aeration basin of a wwtp with industrial wastewater
• With IFL 700 IQ, the ultrasonic sensor for detailed presentation of sludge profile in the post-sedimentation
