The sampling drum utilizes the syringe principle. Before use, first evacuate the air inside the drum, then submerge it in the water body. Once it reaches the desired depth, initiate the suction; the drum will automatically stop once filled.Halt.PreciseComply with the requirements for deep sampling. This sampling method effectively avoids the drawbacks of traditional sampling buckets, such as disturbance to water layers, inaccurate depth measurement, and mixed sampling.

Sample buckets equipped with adjustable depth floats. Once the bucket reaches the preset depth, the float initiates the retrieval, allowing for automatic depth-specific sampling. This sample bucket is widely applicable for environmental water sampling from sources of water pollution, rivers, lakes, reservoirs, and other aquatic bodies.

Pre-emptying, automatic extraction at the arrival of the specified depth, more in line with sampling standard requirements.    

Water samples exhibit no interlayer cross-interference, making the samples more representative.

Due to the pre-evacuation of air within the drum, it can sink without the need for additional weighted sampling drums.

Compact and lightweight for easy portability.

Pure mechanical structure, no power required.   

 Simple operation, stable collection.
