The pH value indicates how acidic or basic a solution is. This is important because the pH value influences many chemical processes, including the solubility of substances and the activity of enzymes. An incorrect pH value can slow down or accelerate chemical reactions and affect the stability of products.
JUMO pH electrodes and pH sensors are used in various fields, including:
1. water and wastewater treatment: monitoring and controlling pH to ensure water quality.
2. food and beverage industry: monitoring pH during production to ensure product quality and safety.
3. chemical industry: monitoring of processes in which the pH value plays a decisive role.
4. pharmaceutical industry: ensuring the correct pH conditions in the production of medicines.
5. aquaristics and swimming pools: monitoring the pH value to ensure a healthy environment for fish and bathers.
In addition, pH is measured in many other areas, including
1. environmental protection: monitoring water and soil to detect and control pollution.
2. medicine: determining the pH of body fluids such as blood and urine to diagnose and monitor diseases
3. agriculture: checking the pH value of soils to ensure optimum growth conditions for plants.
4. cosmetics: ensuring the skin compatibility of products by checking the pH value.
5. food industry: monitoring the pH value during the production and storage of food.

General descriptionThe electrodes are characterised by high mechanical and chemical resistance. Due to the stable PVDF body, there is practically no risk of the sensor breaking. The electrolyte of these combination electrodes guarantees a stable measured value, even in critical media containing sulphite.A Pt1000 temperature sensor is integrated. Depending on the application, the electrodes can be manufactured as pH or redox electrodes. An open annular gap diaphragm is used as the diaphragm.Areas of applicationChemical industryWaste water treatmentSewage treatmentPaper industry
