pH sensor - Aqueous media in general
SC26 - Diffused, shielded type electrode specific for high temperature measurements. Used mainly in industrial processes and water treatment plants, both for pH control systems in pure water, with low ionic activity, as well as contaminated effluents and viscous solutions. It has as a differential an internal system that allows its use in temperatures up to 90 ° C. It can be made with a built-in temperature sensor, providing in addition to the pH measurement, the temperature measurement of the analyzed solution. Important to check the availability of the pH meter used, the type of temperature sensor (PT100 / PT1000 / NTC / others) and the type of connector (BNC / RCA / others).
SC22 - Diffusion-type combined electrode, shielded with industrial plastic body. Due to its acetal construction, the SC22 model is an alternative to pH measurement in water treatment plants where adverse pressure and temperature conditions prevail or where there are strong acids or bases, such as hydrofluoric acid in low concentrations
SC04R - Combined electrode, rechargeable, with saline bridge, also called ion barrier. It is widely used in pH measurements in juices, beers, milk and derivatives and in analytes with risk of contamination, such as organic solvents and sulfides. Specifies for laboratory measurements to allow recharging or replacement of the reference electrolyte.
