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.

Standard-compliant turbidity measurement with ultrasonic cleaning, according to US EPA 180.1 and DIN EN ISO 7027
LAR’s QuickTONultra continually monitors the TNb content of water. Optionally, further sum parameters can be detected, too. At 1,200 °C, samples are completely oxidised and only within 3 minutes the TNb result is determined.
