Description

Product Description

A pH controller is an instrument used to monitor and control the pH of liquids. It is widely used in industrial and environmental monitoring and plays an important role. In industry, pH controllers are widely used in chemical, pharmaceutical, food processing and other industries. It can monitor and control the pH in the production process to ensure the quality and stability of the product. For example, in the pharmaceutical industry, pH controllers can monitor the pH of pharmaceutical products to ensure their safety and effectiveness; In food processing, pH controllers can monitor the pH of food to ensure taste and quality. pH controllers also play an important role in environmental monitoring. It can be used to monitor the pH of water bodies. This APX2-C3 pH meter transmitter has time and historical data?recording function can meet higher data management requirements.

FAQ

1. Can your ORP pH meter realize dosing control?

A: Of course. The APX2-C3A controllers have two SPST relays. The setting objects include: alarms for high and low values of PH/OPR, alarms for high and low values of water sample temperature, and can also be set as a cleaning cycle for the sensor.

2. Does your controller have temperature compensation function?

A: The digital pH meter made by Daruifuno can not only compensate the temperature of the test sample by connecting the temperature sensor, but also self-check the working temperature of the instrument in real time. When the working temperature of the instrument changes, the instrument will compensate the hardware changes caused by temperature drift accordingly, making the detection result more accurate. This is a patented technology.

3. Can your instrument achieve signal output?

A: The APX2-C3A PH meter has a two-wire RS485 interface, the communication protocol is standard MODBUS RTU. It also has two 4-20mA current output.
