Hach's Differential Process pH Sensors (Hach pHD) use a field-proven, proprietary technology to measure online pH with three electrodes instead of the two electrodes that are standard with conventional process pH sensors.
Download the data sheet to learn how Hach's pHD sensors can lead to unsurpassed measurement accuracy, greater reliability, and less downtime and maintenance at your facility.
Hach digital pHD process pH sensors have integrated electronics that “Plug-and-Play” with Hach's sc controllers. The pH sensors are available in a wide variety of body materials, mounting styles, pH electrode types, and cable connections.
Hach will replace any differential sensor that fails due to defects in materials or workmanship within one year from the date of shipment, and on a prorated basis for any failure that occurs up to 30 months after shipment.
