Purpose: To collect underwater sediments (sediment, bottom material, sludge), swamp soil, and mud carbon soil from rivers, lakes, and ponds.

Suitable for a water depth of 5m; Sampling tube length 100cm, diameter 4cm;

Stainless steel cutting head (for routine analysis sampling), engineering plastic cutting head (for heavy metal analysis sampling)

Standard configuration includes 1 T-shaped handle, 1 energy absorbing hammer, 5 1-meter extension rods, 1 sampler (including stainless steel cutting head), 1 spare stainless steel cutting head, 1 engineering plastic cutting head, 2 sampling tubes, 4 spare pistons, 1 anti extension rope, 1 scraper, 1 steel tape measure, 2 wrenches, 1 pair of gloves, and 1 aluminum box.

Usage

1. Thread the piston rod through the fixture, then install the piston onto the piston rod, and insert the piston and piston rod into the sampling tube.

Two sets of cutting heads are installed, and then the cutting heads, sampling tubes, and fixtures are fixed together with steel strips.

Connect the extension rope to the top of the piston rod.

4. Connect the extension rod and T-shaped handle according to the actual situation, and push the piston to the bottom of the sampling tube before sampling.

After determining the sampling location, insert the sampling tube vertically into the water and feel that the sampler is not sinking (the cutting head has already entered the mud). Lift the sampler up by about 10-20 centimeters, and then move it back, forth, left, and right by 10-20 centimeters to determine the new sampling point.

Tighten the extension rope and fix it so that the piston position is relatively fixed. Then, push down the T-shaped handle with force to allow the sampling tube to enter the sediment. After reaching the predetermined sampling depth, fix the extension rope on the extension rod or handle and remove the sampler to complete one sampling.
