Four advantages of portable heavy metal detectors for soil testing

At present, soil safety is a matter of great concern to everyone because only a healthy soil environment can produce safe agricultural products. In soil pollution, heavy metal pollution has the largest impact on crops and agricultural products, and has the greatest impact on people’s health. Obviously, during the current agricultural development process, the use of portable heavy metal detectors to carry out soil heavy metal detection began to become a very important content. At the same time, it has a rapid, low-cost on-site detection of soil heavy metals, but also let it Soil pollution investigation and soil remediation play an application role and effect.

The advantages of portable heavy metal detectors for soil testing are summarized in four main points. One is fast and low cost. The portable heavy metal detector is very small in size, easy to carry, and very simple to use. It is easy to maintain and does not consume reagents. The detection time is very short, and field analysis can be performed. Compared with laboratory analysis, it not only reduces the process of sample disposal, transportation, and various complicated records, significantly reduces the cost of a single sample, but also saves a lot of time. The cost of the cost is less. The second is the ability to analyze large quantities of samples. Portable heavy metal detectors are particularly suitable for on-site inspections of large sample volumes such as soil pollution surveys. The third is to support real-time decision making. The portable heavy metal detector is not only a speed measurement instrument, but also a portable on-site detection instrument. Therefore, in the soil detection process, a portable heavy metal detector can be used to conduct on-site heavy metal screening and determine Pollution elements and pollution levels, quickly and clearly delineate heavy metal pollution areas, and timely determine the extent of soil removal.
The last advantage of the portable heavy metal detector is that the cost can be reasonably controlled. The application of the portable heavy metal detector provides a solution with high accuracy, low cost, and the shortest time for the detection of heavy metals in soil. Therefore, it is more conducive to enterprises or related departments to jointly control costs. It not only satisfies the requirements of scientific analysis experiments, but also quickly prescreens samples to help optimize the laboratory analysis process and reduce the workload of analysis. Therefore, it can be said that the portable heavy metal detector is a very practical soil testing instrument. .

Conical Coffee Grinder

A coffee grinder with a cone-knife grinder places a conical knife disk at the bottom of the machine, and then cooperates with the outer ring knife disk for grinding. The coffee powder produced in this way will be closer to granular, and at the same time, the water absorption path of the coffee particles will become longer, and it will take more time for the inside to contact the water, which will result in the coffee powder being released within the first time. The soluble substances are less, and the concentration will not be too high in a short time.
