Digital Gateway to convert analog Differential pH/ORP sensors to digital output, for connecting to sc digitial controller.
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 measureme
Sensors are available with integral digital electronics or with a gateway module for high temperature (above 70┬║C) applications.
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 replacem
Encapsulated construction protects the sensorΓÇÖs 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
Both the digital and analog pH and ORP differential sensors feature a durable PEEK® body for chemical compatibility with most process solutions. For less aggressive solutions, Hach offers a PPS® sensor in a convertible style for pH and ORP measurement
