The five common problems of wall ground moisture meter

Wall surface moisture meter is widely used in paint and painting stucco, floor laying installation, floor construction, building construction, leak room inspection, chimney cleaning, indoor and outdoor decoration and other industries that need to measure moisture quickly, such as wall surface, floor, wall brick , marble, gypsum board, concrete, mud, etc. for the rapid determination of moisture. . Usually many users and friends will encounter some doubts during the actual operation process. The unified answers are as follows:

Question one: Can a single plasterboard be measured? How thick does the plasterboard need to be when measuring?

Answer: First, we need to understand how this instrument works. The wall ground moisture meter uses the electromagnetic wave induction technology to work. The depth of the electromagnetic wave scanning at the probe can reach 50 mm deep; therefore, when measuring, the gypsum board or other measuring objects must be picked up or superimposed to a thickness of 50 mm or more. Only measure the exact moisture. If you simply measure a piece of plasterboard on a table, the measured data is not only the moisture of the plasterboard, but also the moisture content of the wood table.

Question 2: When measuring concrete and walls, how to place the instrument probe?

Answer: Hold the lower part of the instrument and place the instrument shell roughly parallel to the object to be measured. Gently press the instrument probe against the object to be measured. When the data is stable, it is the moisture value of the material.

Question 3: Do you need to reprocess the data using the wall ground moisture meter?

Answer: The electromagnetic wave on the wall ground moisture meter scans the moisture within 50mm thickness, and the average moisture value of the product within the thickness of 50mm is measured, so no further processing is required.

Question 4: When using the wall surface moisture meter to measure the concrete floor, is it a measure of the moisture of a large piece of concrete, or is it measuring the moisture at the contact point?

Answer: Because its electromagnetic wave scanning radius is 50MM, it measures the moisture value at the contact point each time.

Question 5: Do all the three sensing probes of the wall ground moisture analyzer need to be in contact with the measured object?

Answer: Yes. The three sensors of the instrument need to completely touch the object to be measured in order to effectively form a complete circuit. Only one sensor or two sensors are touched, and the measured data is inaccurate.
