/skin/Product Details


Product Overview:

ORP Online Monitor is a commonly used instrument and equipment, mainly used to accurately measure the pH/redox potential value of liquid media, and is widely used in industry, agriculture, scientific research, environmental protection and other fields.


Measurement Principle:

The measuring electrode is immersed in the solution, and the H+ ions generate a battery voltage between the electrode membrane and the solution. The battery voltage generated by the electrode is proportional to the ORP value. The controller has a built-in microcomputer circuit to obtain the ORP value by measuring the battery voltage.


ORP Standard Solution Configuration

Weigh 10.2g of quinone hydroquinone and add it to 250mL of a standard buffer solution with a pH value of 4.01. Stir well and mix it into a standard solution of 256mV.

Weigh 10.2g of quinone hydroquinone and add it to 250mL of a standard buffer solution with a pH value of 6.86. Stir well and mix it into a standard solution of 86mV.
