This company has expanded its conductivity portfolio with the introduction of the UniCond 4-E digital sensors. The new four-electrode sensors have been designed to deliver highly accurate measurements across a very wide range: a single UniCond 4-E measures from pure potable water to acidic or basic solutions. The sensors are suitable for applications such as clean-in-place and desalination processes, deionization regeneration, industrial processing and wastewater treatment. To minimize signal degredation caused by sensor-to-transmitter cable resistance and capacitance, the units incorporate technology that converts the analog signal into a digital signal. The sensor also contains the company’s Intelligent Sensor Management (ISM) concept. — Mettler Toledo Thorton, Bedford, Mass.
