1. Testing standards and methods

Dissolved oxygen, the common detection methods of dissolved oxygen are, electrochemical method, fluorescence method and chemical reagent method (iodometric method).

The electrochemical method, that is, polarographic dissolved oxygen or membrane dissolved oxygen (HJ / 506-2009), is often used to detect natural water, surface water, and some sewage industries. Features, easy operation, easy to carry, low cost of use, and can realize online real-time detection function.

Fluorescence method, a method for measuring dissolved oxygen based on the principle of fluorescence quenching, is widely used. Features, easy operation, easy to carry, but high cost.

The iodometric method, which uses redox reactions to detect dissolved oxygen in water, is the standard method for measuring dissolved oxygen in water. The characteristic is that the cost is low, but the operation is complicated and the requirements are high. The online real-time detection function cannot be realized.
