The sampling drum operates on the syringe principle. Before use, the air inside the drum is first evacuated, then the drum is placed in the water body. Once it sinks to the desired depth, the pumping starts, and the process automatically stops when the drum is full.Halt, therebyPreciseComply with the requirements for deep sampling. This method effectively avoids the drawbacks of traditional sampling buckets, such as disturbance to water layers, inaccurate depth measurement, and mixed samples.

Tanks equipped with electronic depth gauges allow for real-time monitoring of water level depth, temperature, and sampling status onshore. The tank automatically starts sampling when it reaches the preset depth and stops when full, enabling automated depth sampling.

Especially suitable for fixed-depth sampling in river, lake, reservoir, and other environmental water bodies. 

Equipped with water depth measurement function, can be used as a depth sounder.

With water temperature measurement function, available onshoreObserve water temperatures at various depths.

Features simultaneous display of water depth, water temperature, and sampling status.

Electronic Depth Setting, Depth MeasurementPreciseAutomatically sample at reaching depth.

Pre-emptying and automatic extraction at the arrival of the required depth ensures greater compliance with sampling standards.

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

Due to the pre-evacuation of air inside the drum, no additional weighting sampling drum is needed for submersion.

Compact and lightweight for easy portability.

Battery is replaceable, with extra spares available.Simple operation, stable collection.
