Mounting hardware for pHD sc Differential Sensors. Flow-through mount includes a standard 1-inch tee CPVC.
This field-proven technique uses three electrodes instead of the two normally used in conventional pH sensors. Process and reference electrodes measure the pH differentially with respect to a third ground electrode. The end result is unsurpassed measurement accuracy, reduced reference junction potential, and elimination of sensor ground loops. These sensors provide greater reliability, resulting in less downtime and maintenance.
Sensors are available in four mounting styles: convertible, insertion, immersion, and sanitary.
The unique, replaceable salt bridge holds an extraordinary volume of buffer to extend the working life of the sensor by protecting the reference electrode from harsh process conditions. The salt bridge simply threads onto the end of the sensor if replacement is needed.
Encapsulated construction protects the sensor's built-in preamp from moisture and humidity, ensuring reliable sensor operation. The preamp in the pHD analog sensor produces a strong signal, enabling the sensor to be located up to 1000 m (3280 ft.) from the analyzer.
Both the digital and analog pH and ORP differential sensors feature a durable PEEKâ„¢ body for chemical compatibility with most process solutions. For less aggressive solutions, Hach offers a PPSâ„¢ sensor in a convertible style for pH and ORP measurements.
