A more measured world of water

Cost-effective pH measurement for general applications

The 100 ULTRA-D features a high-volume internal chamber containing a super-saturated electrolyte matrix with a large porous PTFE junction that provides added measurement stability with minimal drift for long-term measurement down to 2 μS/cm.

e measurement of turbidity is a critical measurement in drinking water as it is used to indicate water quality and filtration effectiveness (for example, whether disease-causing organisms are present). ABB's 4690 turbidity sensor paired with the AWT420 transmitter, has been designed specifically for the measurement of turbidity throughout the potable water treatment process.
