Application Background

The DL5ppb dissolved oxygen electrode is a balanced dissolved oxygen electrode that adopts the Ross dissolved oxygen electrode principle, and its biggest feature is that it does not consume oxygen. This has brought many application features, which are widely used in power plants in China.

DL5ppb adopts a three electrode system, with two double wound thin platinum wires for the cathode and anode, immersed in an electrolyte surrounded by a permanent membrane. Simultaneously use silver ribbon as a reference electrode to provide a bias voltage for controlling the reaction.

Features

1. Patent probe

2. Permanent, no need to replace membrane or electrolyte

3. Not afraid of pollution

4. The use is generally not affected by flow rate and does not require mechanical stirring

5. Electroplating effect and electrode loss without cathode

6. Accurate measurement and sensitive response
