Digital Differential pH Sensors

Digital Differential pH Sensors
Hach pHD sc Process pH Sensors with Integrated Digital Electronics for Plug and Play Capability with Hach's Digital SC Controllers.

The inline process pH sensors feature exceptional performance due to the Differential Electrode Measurement Technique. This field-proven technique uses three electrodes instead of the two electrodes used in conventional pH sensors, resulting in unsurpassed measurement accuracy, greater reliability, and less downtime and maintenance.

Hach pH sensors are available in a wide variety of body materials, mounting styles, pH electrode types, and cable connections. PEEK is suitable for most applications, and Ryton is preferred for use in clean water. Use the blue filter bar below to select the right inline process pH sensor for your application.

This instrument connects to Claros, Hach’s innovative Water Intelligence System, enabling you to seamlessly connect and manage instruments, data, and process – anywhere, anytime. The result is greater confidence in your data and improved efficiency in your operations. To unlock the full potential of Claros, insist on Claros Enabled instruments.
