Electric soil samplerIt mainly consists of a single chip intelligent control system and an LCD display circuit, which includes an air pump, a flow meter, a mechanical control valve, a LCD display screen, an AC/DC power supply, a timer, and other parts. When in the shutdown state, press and hold the power button to display the "Welcome to Use" interface, and then release the button. If you need to shut down during the sampling process, press the "Cancel" button to exit, and then press the power button to shut down. After the screen displays the "Welcome" interface, it then shows the "Confirm Sampling Time" interface. The current displayed time is the sampling time for the left and right air paths. The reversed number is the current cursor position.Electric soil samplerWhen sampling, the set sampling time is displayed in the upper corner of the screen, and after the sampling is completed, the screen displays "Sampling completed". During the sampling process, you can also press the "pause" button to stop the work, excluding the time to stop sampling. Press the "Sampling" button again to resume sampling, and press the "Cancel" button during the sampling process to exit sampling and return to the time setting interface. Press the power button once to end when shutting down.
Open the sampling grab and place a rod into a hook while opening it. The sampling grab will not be tightly closed. Slowly place the sampling grab into the pool by pulling the rope. When reaching the bottom of the river, the rope, rod, and hook will automatically release under the action of the spring. When sinking it to the predetermined depth, place a falling iron block to strike the back of the lever, lift the front end of the lever, break the glass tube, and allow seawater to enter the water collection bottle.Electric soil samplerAttach a thick walled rubber ball and, when inverted, pull down the plug on the ball mouth, allowing seawater to enter the rubber ball. The sterile water collection bag consists of a sterile plastic bag and a water collection rack. When the water collection bag sinks to the predetermined water collection depth, the hammer or cutter opens the water nozzle and seawater flows in. Mud collectors and cylindrical sampling tubes can also be used to collect microbial samples from the sediment.
