Automatic water quality detection equipment for swimming pool water treatment systems mainly includes: online pH monitor, online free chlorine monitor, online residual O3 monitoring equipment, ORP detection probe, temperature controller, water quality monitoring/control instrument. Automatic water quality detection equipment is usually used with automatic chemical dosing equipment such as metering pumps. Temperature controllers are usually used with heating equipment. Equipment for monitoring ozone content in the air is required when using ozone. Swimming pools should be equipped with manual detection methods, usually using water quality test kits.
The online pH meter is a highly intelligent online continuous monitoring instrument, consisting of a sensor and a secondary meter. It can be equipped with a three-composite or two-composite electrode to meet the needs of various application scenarios. After being equipped with pure water and ultrapure water electrodes, it can be used for pH measurement of water quality with conductivity less than 3μs/cm (such as chemical makeup water, saturated steam, condensate, etc.).
The temperature controller utilizes the principle of thermal expansion and contraction of thermosensitive liquid and the incompressibility of liquid to achieve automatic adjustment. When the control temperature rises, the thrust generated by the expansion of the thermosensitive liquid will heat medium valve smaller to reduce the output temperature; When the control temperature decreases, the thermosensitive liquid contracts, and under the action of the reset device, the heating medium is opened larger to increase the output temperature, so that the controlled temperature reaches and maintains within the set temperature range.
By detecting the pH, residual chlorine, O3, and ORP indicators of the pool water, and sending the detected values to the water quality monitoring/control instrument, the water quality monitoring/control instrument automatically alarms, displays, adjusts, and controls related equipment, thereby realizing the system's water quality maintenance function.
