DESCRIPTIONS

Water sampler: It consists of two parts: the water sampler barrel and the counterweight ring! It is specially used for field water sampling, and is used for collecting water samples within a depth of 0-30m in rivers, lakes and reservoirs.  Operation Steps and Requirements: (1) Before sampling, place the prepared latex tube over the water outlet of the water sample collection bottle and clamp it with a flatjaw pinchcock, make the outlet of water sample collection bottle close. (2) Select a sampling rope suitable for the sampling depth and firmly tie it to the beam of the water sampler. Make the water sample bottle sink into the water source to be sampled at a constant speed of no more than 1 m/s. (3) The sample is injected from the bottom of the water sampler, and the sample is continuously replaced from the top displacement port. When the water sampler stops at different depths in the container, the sample taken is the sample that represents this depth. (4) When the water sampler sinks to the required sampling depth, the bottom valve and the top cover automatically close. (5) Slowly lift the water sampler, do not touch the bottom inlet to avoid sample leakage, take out the water sampler, open the water stop clip, transfer the obtained sample to the - sample container, the sampling is finished.
