A: Our soil sampler is made of iron-manganese steel. It is more reliable to remove grease from the sampler before taking soil, and then remove contaminated soil samples. Not only the analysis of some trace elements in the soil will not be affected (such as: cadmium, copper, vanadium, chromium, nickel, etc.), and the analysis of iron and manganese in soil is also very reliable. However, after removing the soil sample, it cannot be stored in a humid environment for a long time. If the mud on the surface of the auger is seriously oxidized, it will affect the analysis of some elements such as iron and manganese. Note: Neutral baby shampoo or water can be used when taking soil again.
2, soil sampler can be extended a few meters normal?
Answer: Normal can be extended by 4 meters without bending. While drilling down, it is necessary to connect the coupling of one section of the extension rod. The soil sampler extension rod uses a coupling-linked, non-threaded connection, which is more secure and reliable.
3. How to effectively clean the soil sampler after the soil sampler is used to take contaminated soil?
A: You can use Deconex concentrate with hot water at 60-95 degrees, then rinse with water. Or use a neutral baby shampoo and rinse with water.
How to choose the right soil sampler?
Answer: The first kind of soil type that you need to take soil sample, soft soil or hard soil, the depth of sampling. The relatively large soil hardness of the soil is generally used in small diameter, can be directly hit the sampler into the soil with a hammer, remove the soil (such as the German STEPS42090). Soft soils are generally used for manual soil-drilling to extract the soil, and according to the soil type, an earth-boring drill bit (such as 42101 type earth drill) is selected.
CZ Purlin Forming machine,we can tell from its name,that means one machine can make c purlin and z purlin both.It is very easy to convert from c purlin to z purlin or z purlin to c purlin.Automatic control while changing different sizes.
The final product can be cut as per set length controller,and the length is automatically measured by encoder.When final product reached set length,machine will stop to cut the sheet automatically.Finish thhis action,the machine will run again continuously
