Increase the accuracy and efficiency of your pH measurements
In the chemical industry, pH should be measured in various applications, such as in the water treatment process or in chemicals produced for the human body in pharmaceutical applications. In this case, pH measurement requires the highest accuracy and the pH meter should be chosen very carefully, so as not to jeopardise entire batches of product.
The base materials – rock salt, ethylene, propylene, methanol, acetate, phenol and aniline – are subjected to a long series of integrated processes and manufacturing stages to produce finished products. Over the course of these processes, wastewater with a high level of salt content is generated. With a temperature of 90 °C and a pH value of 1 – 1.5, this wastewater passes through a pipeline at 1.5 bar. Regular cleaning and calibration of the pH electrodes at this measuring point are essential to permanently maintain reliable pH measurements.
pH in sodium bisulfite
Sodium bisulfite is used as a preservative and antioxidant agent in the food industry. An important quality attribute of this agent is the pH value, which needs to be monitored constantly. Sensors in this application have to be calibrated regularly. When choosing the right sensor for this application, ease of calibration is an important aspect to ensure the most time-efficient solution. Using analog sensors won’t be a cost-efficient solution, as the lifetime of those is very short and the calibration time consuming. Sulfuric acid production also has the same pH sensor requirements; considering those factors you can choose the most effective solution so as to increase the quality of the products and the speed of your processes.
