Features & Benefits:
Exceptional Performance with the Differential Electrode Measurement Technology + | -
This field-proven technique uses three electrodes instead of the two used in conventional pH sensors. Process and reference electrodes mesure the pH differentially with respect to a third ground electrode. The 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.
Extended Working Life with Replaceable Salt/Bridge Protector + | -
By replacing the salt bridge and standard cell solution, Hach Differential Sensors can be regenerated for repeated use. 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.
Reliability with Built-in Encapsulated Preamp + | -
Encapsulated construction protects the sensors built-in preamp from moisture and humidity, ensuring reliable sensor operation. The preamp amplifies the signal from the probe to the controller. The preamp in the pHD analog sensor produces a strong signal, enabling the sensor to be located up to 1000m from the analyzer
Connect to Hach sc Controllers through Digital Gateway + | -
There are no complicated wiring or set up procedures with any Hach sc controller. Just plug in any combination of Hach digital sensors and it’s ready to use— it's "plug and play." See Hach sc Controllers
Durable Body Materials + | -
Sensors feature an LCP (liquid crystal polymer) body ideal for most applications due to chemical resistance and mechanical strength. These sensors can be used in aggressive process solutions such as acids, bases, alcohols, hydrocarbons, aromatics, chlorinated hydrocarbons, esters, ketones, and most other chemicals. For less aggressive solutions, Hach offers a Ryton® sensor, which is best suited for measuring strong base solutions of more than 12 pH at elevated temperatures. It can also be used in acidic solutions, but is not recommended when aromatic hydrocarbons are present.
Versatile Mounting Styles + | -
Sensors are available in convertable and union mounting styles.
Differential Sensor Warranty + | -
Hach Company offers the best sensor warranty in the industry on its Differential Sensors. We will replace any Differential Sensor that fails due to defects in materials or workmanship within one year from the date of shipment - and up to 30 months on a prorated basis for any failure.
