wholesale steel asphalt sampler

The bottom sampler is also called bottom valve sampler, bottom sampler for liquid petroleum products.

The bottom sampler conforms to the national standard of GB/T4756 manual sampling method for petroleum liquids and GB/T6680 general rules for sampling liquid chemical products. It is suitable for samples of oil storage tank, tank car and other parts.

The bottom sampler is made of brass and stainless steel.

The specifications of the bottom sampler are 165ml, 330ml, 500ml and 1000ml.

A description of the bottom sampler:

1. One end of the static proof sampling rope is firmly grounded, and the place can not have insulating paint. The other end of the static proof sampling rope is firmly connected with the bottom sampler.

2. Touch the tank before sampling, so as to eliminate static electricity.

3. The bottom sampler falls to the bottom of the container at a speed of not more than 1 meters per second. When the bottom valve is touched at the bottom of the container, the bottom valve opens and the oil will have bubbles when entered in. Put out the bottom sample when the bubble is free. Then the sample can be collected. Dry it after sampling.

4. When the bottom sampler is put forward, the bottom sampler should not touch the metal oil tank as far as possible so as to avoid electrostatic discharge.

5. During the whole sampling process, the bottom sampler, the static proof sampling rope and the grounding points must be firmly connected to eliminate the static electricity.
