Most pH sensors with a glass membrane cannot be mounted upside down. To absorb the thermal expansion of the internal buffer solution there is always a sizeable air bubble inside the sensor. When the sensor is mounted upside down the reference element can lose contact with the electrolyte. The FU24 pH sensor from Yokogawa can be used in upside down application, because it has a special design that allows us to reduce the size of the air bubble. The PH18 sensor can be mounted upside down because it does not have a glass electrode or electrolyte.
The FU24F is a digital SMART pH/ORP sensor made with a chemical resistant PPS 40GF body for harsh pH applications.
The cation differential pH and ORP sensors were designed for difficult applications where conventional sensors are ineffective. These include measurements such as brine solutions to applications as diverse as electrolysis processes and cheese manufacturing.
Process analyzers are on-line tools for industrial process analytics. They are used to determine the chemical composition or physical properties of substances involved in industrial processes. They enable process optimization, asset protection, and compliance with environmental regulations.
Liquid analyzers are used for monitoring process chemistry including water quality, providing process optimization and control.
pH and ORP meters, analyzers and transmitters are used for continuous process monitoring of pH and ORP to ensure water/product quality, monitor effluent discharge, batch neutralization, pulp stock, scrubbers, cooling towers, chemical, water/wastewater treatment and many other applications.
pH electrodes and sensors are the sensing portions of a pH measurement. Various installation options including retractable, flow thru, immersion, and direct insertion. Proper pH electrode/sensor selection is critical for optimal measurement results.
