Digital pH/ORP Meter for Water Testing

SISCO-PHM-PH160

The digital pH/ORP meter is a pH/ORP controller for testing water quality, which can transmit the standard output signal 4-20mA to the digital panel meter/VFD/PLC/logger, or transmit the RS485 signal to the computer for remote monitoring and recording. The pH meter works for testing and monitoring the pH of sewage, corrosive solutions, liquid pharmaceuticals, beer, drinking water, food, etc.

pH Controller for Water/Food Process

SISCO-PHM-PH6

The pH controller transmits the standard output signal 4-20mA to the digital panel meter/VFD/PLC/logger, or transmits the RS485 signal to the computer for remote monitoring and recording, which is widely used in the test of water/food pH or ORP value and monitoring.

The pH meter works on the principle of a primary cell, where the electric potential between the two electrodes is related to both the electrodes' own properties and the concentration of hydrogen ions in the solution, according to Nernst's law. There is a correspondence between the electric potential of the primary cell and the hydrogen ion concentration, the negative logarithm of the hydrogen ion concentration being the pH value.

pH meters/controllers are instruments used to test and monitor the pH of solutions, they usually have a digital reading and can provide a value in the range of 0 to 14. A reading of less than 7 indicates an acidic solution, while a reading greater than 7 indicates an alkaline solution. pH meters are commonly used to test the water in boilers, cooling plants, and water treatment plants.
