HJ 802-2016 《Soil quality.Determination of conductivity.Electrode method》 Related products

This standard specifies the electrode method for determining soil conductivity, which is applicable to the determination of air-dried soil conductivity. Soil conductivity refers to the ability of soil to conduct current, which is expressed by measuring the conductivity of soil extract. The term defines the Conductivity detector pool constant, which is an important physical constant for measuring the conductivity of a Conductivity detector pool, expressed as Q. The principle of the method is to take a naturally air-dried soil sample, add water and shake the extraction, and measure the conductivity of the extract at a specific temperature. According to the Conductivity detector pool constant Q and the resistance value of the extract, the conductivity can be obtained.
