The main purpose 
 Field water samples dedicated for rivers, lakes and reservoirs and other surface water within the 0-30m depth of water acquisition. 
 Technical parameters 
 Mining bottle body: PMMA material, with heavy lead weights, upper and lower lid can be easily flipped to achieve opening and closing; 
 Capacity: 1000mL, 2500mL, 5000mL 
 Sampling depth :0-30m; 
 Thermometer: measurement error ± 1 ℃; 
 Plexiglass water harvesting device: the barrel, with the axis of the two semi-circular roof and floor activities, such as the composition of sea water samples collected for the sea. 

 Applications 
 Mainly used for collecting samples of aquatic organisms, but also applies in other bacterial indicators and oil quality sample collection. Phytoplankton sampling, water harvesting device can be used plexiglass. (Note that when using the outlet hose clamp first, then the two semi-circular roof open. To adopt water heater into the water at the bottom of the inlet is automatically turned on. Can collect water samples from different depth layers, the above system a rope , the following water, above water, water harvesting, when the device stopped at different depths, the water samples taken, this is the level of water samples. subsidence depth should be marked on the tether, when sinking the required depth, ie, put on the tether, under cover, and automatically close the inlet, from the water, do not touch, and under the bottom to avoid leakage of watery diarrhea. the mouth of the outlet hose inserted into the container, loosen the iron clamp, water is injected into the container .) quantitative sampling, in still water and slow flow of water used plexiglass sampler collection.
