Industrial Wastewater Treatment: It is suitable for monitoring the pH value of wastewater in industries such as chemical engineering, metallurgy, and electroplating. The automatic temperature compensation function (0～80℃) can ensure accurate detection even when the wastewater temperature fluctuates, helping enterprises adjust the dosage of neutralizers in a timely manner to meet environmental discharge standards. Meanwhile, the dual-set point and relay control functions can trigger alarms or start/stop related treatment equipment automatically when the pH value is abnormal, realizing intelligent wastewater treatment management.

Aquaculture Industry: Used in fish ponds, shrimp ponds, and other aquaculture water bodies to monitor the pH value in real time. The wide measurement range (0.00～14.00pH) covers the suitable pH range for most aquatic organisms. The 4～20mA DC output signal can be connected to the aquaculture control system to transmit data remotely, allowing breeders to grasp the water quality status in time. When the pH value is too high or too low, the relay can drive aeration equipment or acid-base adjustment devices to maintain the stability of the aquaculture water environment and improve the survival rate of aquatic products.

Food and Beverage Processing: Applied in the production process of beverages, dairy products, and pickled foods. For example, in the brewing of fruit juices, it is necessary to monitor the pH value of the raw juice and the finished product to ensure the taste and quality of the juice. The high input impedance (>10¹²Ω) and low input current (<2pA) of the transmitter can avoid interference with the measured solution, ensuring the accuracy of detection results. In addition, the device's small size (105×95×58mm) and DIN standard rail installation method make it easy to integrate into the existing production line control cabinet, saving installation space.

Laboratory Testing: As a stable and reliable pH detection tool in chemical laboratories, environmental monitoring laboratories, etc., it is used for the pH measurement of various experimental solutions. The LCD display can clearly show the detection data, and the adjustable relay action delay (0～40 seconds) can meet the different response time requirements of various experiments. The removable terminal block facilitates the connection and replacement of electrodes, impAméliorer l'efficacité des opérations expérimentales.
