2 SPST 14pH Online PH ORP Transmitter With Sensor Diagnosis Function
In our daily life, ph is an important measurement index. Detergents, food, sewage treatment, chemicals, plastic products, pharmaceuticals, papermaking, etc. are all related to pH. ORP is a comprehensive indicator. It is also essential in the monitoring of water quality. The excellent cost-effective pH ORP transmitter can monitor pH and ORP values at the same time, realizing accurate ORP measurement within ±2000mV range and pH measurement within -2~16pH.
Introduction Of The PH ORP Transmitter
-
The instrument is equipped with shortcut keys, and daily necessary maintenance can be performed without entering the menu, and the operation is convenient.
-
The APX1-G2D has 128*64 large screen graphic dot matrix LCD screen, multi-language display options, rich content;
- The PH ORP transmitter 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.

Advantages Of The PH ORP Transmitter
1. There are 2 configurable 0/4~20mA active current loop outputs. Each current output allows the user to specify what measurement value, pH, ORP, or corresponding temperature represents. At the same time, each output can define the range of output value corresponding to the maximum and minimum current value by itself, whether it is forward or reverse correspondence, it is all right.
2. As the temperature of the aqueous solution changes, the concentration of hydrogen ions and hydroxide ions ionized from the aqueous solution will also change. This pH ORP transmitter has a temperature automatic compensation function, and when the temperature of the instrument changes, it will also compensate the hardware changes caused by temperature drift.
Applications Of The PH ORP 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.
