Description

Technical Field

[0001] This utility model relates to the technical field of ammonia sampling equipment, specifically an ammonia sampling device that automatically removes residues from the material cylinder. Background Technology

[0002] Raw materials usually need to be sampled and tested when they enter the factory. For example, ammonia water needs to be tested for concentration using an ammonia water sampling device when it enters the factory. However, the existing ammonia water sampling devices still have certain defects in use, such as:
