Two SPST Relays RS485 Modbus PH ORP Meter For Dosing Control

Two SPST Relays RS485 Modbus PH ORP Meter For Dosing Control

The pH ORP controller APX1-G2A is an instrument that continuously monitors the pH and ORP of a solution. It is used for continuous measurement of industrial processes and has both alarm and control functions. The pH of the neutral solution is 7, the pH of the acidic solution is less than 7, and the pH of the alkaline solution is greater than 7. By measuring the pH value of the wastewater, it is possible to determine the current pH of the solution, and then determine the amount of neutralizer to choose and how much to choose, so that the wastewater treatment process can be more clear.

Brief introduction:

• The measurement principle is the pH glass electrode measurement method;

• Large-screen LCD display, Chinese and English language selection, the screen displays the pH value, temperature, electrode type, relay status, and other parameters;

• The PH ORP controller with differential signal input is compatible with the DRFN pH sensor with grounded electrode;
• The housing protection grade is IP66, it can effectively isolate the pollution of the external environment;
• There are 2 SPST multifunction relays that can be set;
• There is a two-wire RS485 interface, the communication protocol is standard MODBUS RTU, and it also supports JavaScript Object Notation text data format.

Aplication:
Water treatment monitoring
Drinking water,surface water,water quality analyze,ground water,ect.
 
Industrial process monitoring and dosing control
Chemical,petroleum,paper,food and medicine,PCB manufacturing,etc.

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.
