Modbus Or Jason Protocol PH Controller With Historical Data Recording Function

Modbus Or Jason Protocol PH Controller With Historical Data Recording Function

Continuous monitoring data of the APX2-C3A/C3D can be connected to the recorder through the transmission output to realize remote monitoring and recording. It can also be connected to the RS485 interface through the MODBUS-RTU protocol, which can be easily connected to the computer to realize monitoring and recording. 

It adopts a design that is easy to operate, adopts a variety of self-diagnosis and output signal, alarm functions, and can carry out communication and control, data storage, and inspection of the detector.With data record function can Record 14,000 historical data; Save the last 100 maintenance data. 

The built-in program has menu functions such as current output for control and electrode cleaning cycle program.

FAQ
Q1. Does the instrument have a self-diagnostic function and how does it prompt?
A: The pH meter has self-diagnosis function.When the instrument is in calibration and maintenance,it can diagnose the PH/ORP sensor,if there is improper operation or poor PH/ORP sensor characteristics, the screen makes an image display and advises the user to re-maintain or replace the sensor.

Q2. What are the special advantages of the pH instruments?
A: The instrument 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 compensates the hardware change caused by the temperature drift. Make the test results more accurate, this is a patented technology.
