RS485 Interface Electrical Isolation PH Probe For Industrial Process Measuring

 PH digital sensor can directly output RS485 signal and 4-20mA signal; the product has good accuracy, good stability and strong anti-interference ability. Automatic temperature compensation function.

Without the need for instruments, it can be directly connected to computers, PLCs and other equipment with RS485/4-20mA signal interfaces for data collection and maintenance; it is convenient for users to integrate sensors into the host computer system and the Internet of Things and other industrial control environments.

The sensor can be set through RS485 communication, such as slave address and baud rate, online calibration, factory reset, 4-20mA output corresponding range (4-20mA is optional), proportional coefficient and incremental compensation. A two-point calibration method was used. Power failure protection>10 years.

FAQ
1. What is the measurement principle of this pH electrode?
A: The pH value potentiometric method uses the potential difference of glass electrodes for pH measurement.

2. How to judge the pH of the solution?
A: If the internal hydrogen ion concentration of the pH glass bulb is lower than the outside, the measured solution is recorded as acidic and the pH value is lower than 7; if the two are the same, the solution is neutral and the pH value is equal to 7; if the internal hydrogen ion concentration is higher than externally, the measured solution is alkaline and the pH value is higher than 7.

3. What is the wire length of the pH electrode?
A: The lead wire of this electrode is 1 m by default, other lengths need to be customized, contact our customer service, the price will vary with the change of length.
