1、 Purpose:

A soil solution sampler is a device used to extract soil solution samples from soil.

Sampling tubes can be installed at different burial depths to meet the needs of soil solution sampling at different depths. The extracted soil solution can be subjected to multiple studies, such as soil solution composition analysis, salt analysisPH value, heavy metal, pesticide, herbicide content, etc.

2、 Working principle:

The sampling head is hydrophilicPE and microporous nylon are made by special treatment (sintering), and this material has no adsorption of heavy metal components in the solution. It is suitable for the analysis of heavy metals, herbicides, pesticides and other components in soil solutions. After providing a certain negative pressure to the soil moisture sampler with an electric vacuum pump, soil solution samples can be obtained.

3、 Composition:

1. Soil solution sampling tube: The sampling head is made of hydrophilic PE and microporous nylon through special treatment (sintering), and the sampling tube has different lengths for different depths.

2. Sampling bottle: used for storing and retrieving soil solution samples, and also serves as a negative pressure device buffer bottle; Equipped with a check valve.

3. Electric vacuum pump: portable design, easy to carry in the field, built-in battery, with negative pressure gauge.
