Description

Technical Field

[0001] The utility model relates to the technical field of sewage detection, in particular to a sealed sample collector for sewage detection. Background Art

[0002] The sewage sampler adopts a high-reliability peristaltic pump and a hybrid stepper drive to meet the water quality sampling requirements under various environmental conditions. It is suitable for environmental monitoring stations at all levels, sewage treatment plants, water conservancy, water affairs and scientific research institutes to collect water samples from industrial sewage outlets, rivers, lakes and seas.
