How to choose a pH sensor for high temperature and high acid-alkali environment?

In some special industrial environments, the solution will be highly acidic or highly alkaline, and usually accompanied by high temperature, exceeding 100°C. In this case, ordinary pH sensors used in surface water, sewage and wastewater environments are not suitable. So how to choose a PH Sensor that can be used in high temperature and high acid-base environment? The ASP125E pH glass electrode developed and produced by Daruifuno is designed for special industrial environments. The pH electrode has a special design in terms of structure and material, and can be used directly in a high temperature environment of 130°C, but please note that the time should not exceed 60 minutes. The electrode is also resistant to acid and alkali, and can work in the environment of strong acid and strong alkali.

Features:
Glass shell pH composite electrode, low impedance cylindrical glass membrane
Large sensing area, fast response, high strength
The reference adopts ceramic hole sand core, which is not easy to be blocked, and the reference electrode is Ag/AgCl
One lead wire, easy to use; separate plug and pull is convenient, you can choose according to your needs
With temperature unit, NTC10K, PT100, PT1000 customized
No need to replenish electrolytes, low maintenance

High-temperature-resistant pH electrodes usually use special high-temperature glass materials, such as borosilicate glass or high borosilicate glass, to improve their high-temperature resistance. The reference electrode should also use special materials, such as platinum-platinum-iridium alloy, platinum-platinum-palladium alloy, etc., to improve its high temperature resistance and chemical stability. The conductive cable of the high-temperature-resistant pH electrode is usually made of high-temperature heat-resistant materials, such as polytetrafluoroethylene (PTFE) or silica gel, to ensure the stability of electrical signal transmission in high-temperature environments.

In addition to high-temperature acid and alkali-resistant glass electrodes, we also have other pH electrodes for special industrial environments, such as hydrofluoric acid-resistant pH electrodes, pH electrodes for desulfurization environments, high-temperature fermentation pH electrodes, low-temperature resistant pH electrodes, pure water pH electrode, etc. If you have any needs, you can contact us for model selection.
