Product details

Product Overview

ORP online monitoring device is a commonly used instrument equipment, mainly used for precise measurement of the pH/redox potential value of liquid media, widely used in industries, agriculture, scientific research, environmental protection and other fields.

Measuring Principle

The measurement electrode is immersed in a solution, and 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 built-in microcomputer circuit of the controller obtains the ORP value by measuring the battery voltage.

ORP standard solution configuration

Weigh 10.2g of quinhydroquinone and add it to 250mL of standard buffer solution with PH value of 4.01, mix it evenly and prepare it into 256mV standard solution.

Weigh 10.2g quinhydroquinone and add it to 250mL of standard buffer solution with PH value of 6.86. Mix it evenly and prepare it into 86mV standard solution.

Instrument Features:

Dot matrix LCD screen display

Intelligent menu operation
