The pH of fluids is a critical factor in countless industrial operations, including food processing, waste management and water purification. Therefore, if you are planning on establishing a system where alkalinity or acidity of fluids could influence your industrial processes, invest in a pH controller. As implied, a pH controller will monitor the potential hydrogen in your fluids. Moreover, the unit will adjust the pH if the measurements are not at the optimal level. Keep in mind that the core performance of different products will vary. If you are concerned about choosing the right pH controller, consider these factors before purchase.

Operating Conditions

When choosing a pH controller, ensure that the chosen unit is compatible with the operating conditions in your industrial premises. If the conditions are too harsh for the installed component, your investment will be lost. For instance, the controller could sustain damage or experience accelerated wear. Inquire about the maximum operating temperature and pressure of the controller. Also, check on its sensitivity to different chemicals. Additionally, consider any legal regulations imposed for the tools used in industrial processes. For example, if you are involved in food production, the probe must be safe.

Installation Requirements

A good pH controller must be easy to install in the industrial system. If the component is complicated, the risk of installing incorrectly will increase. A faulty setup will lead to erroneous measurements during operations. Consequently, the pH might not be adjusted to the desired levels. If the problem is ignored, the quality of your products will decline, and your equipment could sustain damage or wear. Therefore, opt for a simple design. If possible, acquire a pH controller that does not require assembly. A factory-assembled component will allow for intuitive placement.

Monitoring Options 

The monitoring options for pH controllers will determine the convenience afforded after purchase and installation. Simply speaking, a good component should allow for maximum expediency, eliminating the need for constant manual check-ups. Therefore, discuss the monitoring features available with your equipment supplier. For instance, remote monitoring with a computer or smart devices applications is favourable. This option is ideal because it eliminates the need for onsite workers to check the gauges. Remote check-up could also improve workplace safety due to minimal contact with process machinery. Also, consider the importance of an alarm or other notification system. This type of feature will supply information in case of pH anomalies. Additionally, inquire about the options for adjusting pH or making system changes remotely through the use of a dosing pump or other accessories.
