14pH Online ORP PH Transmitter Accurate PH Meter For Continuous Measurement
When the ratio of OH- in the solution is greater than H+, the solution is alkaline. When the ratio of OH- in the solution is less than H+, the solution is acidic. The pH value of the solution can be obtained by measuring the H+ activity in the solution. ORP is a comprehensive indicator. It is also essential in the monitoring of water quality. The APX2-C3D is an online ORP PH transmitter for the measurement of pH and ORP.
Introduction Of The ORP PH Transmitter
- IP66 enclosure protection grade can isolate external pollution;
- 3.2-inch display screen, 128*64 black and white graphic dot matrix LCD;
- The material of the housing is enhanced ABS, it makes the ORP PH transmitter more strong and wear-resistant;
- Abundant output, meeting PH/ORP monitoring, dosing control, remote data signal transmission;
- The menu password can be set to facilitate hierarchical management;
- 2 settable SPST multifunction relays and 2 configurable 0/4~20mA active current loop outputs;
- A two-wire RS485 interface, standard MODBUS RTU, supports JavaScript Object Notation text data format.

Product Advantages
1. The ORP PH transmitter accurately travels the time according to the year, month, day, hour, minute, and second, and records the measurement data on time to form historical data that can be consulted. The instrument can record up to 14,000 historical measurement data, and the recording interval is freely set by the user. The user's maintenance operations on the instrument will also be recorded, and the last 100 maintenance data will be saved. These contents help us to find and analyze the cause when the instrument is found to work abnormally.
2.The ORP PH controller can not only compensate for the temperature of the test sample by connecting the temperature sensor but also self-check the working temperature of the instrument in real-time.
3.The ORP pH transmitter has self-diagnosis function, if the operation is improper or the PH/ORP sensor is not good, the screen will display the image and the buzzer will prompt briefly.
Applications Of The ORP PH Transmitter
Water treatment monitoring: Drinking water, surface water, water quality, groundwater, swimming pool, etc.
Industrial process monitoring and dosing control management: Chemical, petroleum, paper, food and medicine, electroplating, PCB manufacturing, etc.
