Product overview
PCPH02 meter is an instrument independently developed by our company for online monitoring of pH/ORP value and through the
current analog output to the monitoring room for record preservation. pH /ORP controller is widely used in thermal power, chemical
fertilizer, metallurgy, environmental protection, Pharmaceutical, biochemical, food and water industries and for solution pH or ORP
Values and temperatures are continuously monitored.The continuous monitoring data can be recorded by remote transmission through
substation and output connection.

To achieve the best possible accuracy, the calibration should cover the range of the desired measurement values. If the readings go beyond
the calibrated range, the pH meter assumes linearity and simply extrapolates the value to be displayed. The true value may be slightly different.
More advanced pH meters will let the user calibrate at three, four or five and even higher numbers of pH values. A multi-point calibration mean,
in comparison to a two-point calibration, that you can calibrate your pH tester on both sides of the zero point (pH 7.00). This will expand your
pH measurement range without the need of re-calibrating.
