Firstly, loosen the round nut once, thread the hose through the nut, then tighten the nut and secure itCap type water collectorThe connector and hose extend 1 centimeter from the sampler connector into the sample bottle to prevent contamination from the connector and internal liquid. Twist the sample bottle onto the sampler connector. Insert the hose into the liquid and pull the handle back and forth to create a vacuum inside the sample bottle, allowing the liquid to flow into the bottle along the hose. When the liquid enters the largest mark in the sample bottle, stop sampling. Do not fill the sample bottle with liquid. Unscrew the sample bottle from the sampler connector, attach the lid, and be careful not to mix dust. If the negative pressure is not idealCap type water collectorAdd a small amount of lubricating oil to the piston.

It can be used separately or in conjunction with temperature depth or temperature salinity depth sensors to collect water samples at the desired depth while measuring temperature, depth, or temperature, salinity, and depth. The bottle body is equipped with a scale, which can collect water samples of different volumes according to needs, making it convenient to use,Cap type water collectorEquipped with a built-in thermometer, it can observe the temperature of water samples in real time. The bottom of the bottle has a side water outlet for easy sampling, and the water outlet is made of high-strength nylon material. Before use, check whether the sampler is clean, whether the upper cover and lower bottom are tightened (tighten when threading), and whether the valve is closed. Drop it freely to the sampling depth, quickly lift it up and down 2-3 times, and remove the sampler to complete the sampling. Translate into EnglishCap type water collectorLift the lid and pour the liquid into an open container. Complete the transfer of the sample, clean the sampler, and wipe dry with a cloth.
