The Model T80 transmitter digitally communicates with any ECD S80 digital sensor, automatically configuring the transmitter’s menus... more
  • The user-friendly and economical CDA-22 chlorine dioxide analyzer simplifies the monitoring and control of chlorine dioxide in applications for the food and beverage industry, including clean-in-place sanitizing and rinsing operations. With a panel mounted plumb-and-play design and automatic flow control, the CDA-22 is a low-maintenance, complete chlorine dioxide measurement system. more
  • The Triton TR6 is a nephelometric sensor that is designed for the analysis of turbidity or suspended solids in water and wastewater. It is available in two optical configurations—one with side-mounted optics and one with axially front-mounted optics. more
  • Process and plant engineers seeking a lower cost and maintenance solution will find the answer with the advanced Sentinel predictive maintenance technology from the T80 Universal Transmitter and S80 Intelligent Sensors. This technology alerts maintenance technicians to sensor electrode (pH, ORP, selective Ion) wear so that sensor electrodes are replaced only as necessary. Sensor replacement costs... more
  • The ECD Triton DO80 optical dissolved oxygen sensor combines the high technology of fluorescence quenching with a rugged, easy-to-install design. The DO80 provides a solution for long-term measurements in aeration basins, aquaculture and all types of environmental water. more
  • S80 digital sensors are designed for use with ECD digital analyzers. S80 sensors convert the analog signals from pH, ORP, pIon, dissolved oxygen or conductivity electrodes into a digital protocol that allows two-way communications with the transmitter. more
