Model PHS25 pH & ORP Sensor
Click on part number above to request an RFQ or place an order online.

One sensor serves all installations - insertion, submersion, and flow through
Teflon body is highly resistant to coating and chemical attack
Built for process service but priced for general purpose use
This sensor was designed to give reliable service in the toughest of process environments, yet is priced competitively with those limited to use in less severe applications, such as wastewater monitoring, cooling tower control, and potable water treatment.
Application Notes
Wetted materials of construction are Teflon and Kynar, with EPR seals. The Teflon body provides outstanding chemical resistance, and the no-stick surface greatly reduces or eliminates coating problems. It can hold many different kinds of electrodes, tailored to specific needs, and can be used in any of the three common mounting arrangements. Using an SDI interfacing pH amplifier allows the sensor to work with any major brand of pH or ORP meter now being sold in this or other countries.
These combined features make the PHS25 an ideal choice to standardize on for a facility, eliminating the need to stock many different kinds of electrodes and spare parts. As a further plus, the replacement electrodes can be used in SDI's Easy-Out pH sensor, and, with adapters, in several others as well.
