A magnetic test rod with a diameter of 26 mm is used for checking and testing the presence of metal and magnetic impurities in the selected material. It can be used for dry mixtures as well as liquid substances. Inside, there is a magnetic core with strong NdFeB magnets with sufficient power for testing magnetic impurities. By using circular movements, it is possible to test whether the material contains magnetic impurities. These are captured on the functional half of the rod. To remove them afterwards, simply pull the handle and the impurities will automatically fall off the surface of the rod. You do not need to clean anything manually in a lengthy way.
The test magnetic rod is made of stainless steel according to DIN 1.4301 /AISI 304 / ČSN 17240 standards with a polished surface finish. Its weight is 1.1 kg. The diameter of the magnetic part is 26 mm and the length is 150 mm. The magnetic test rod is equipped with neodymium magnets with a pull-off force of 102 N.
Procedure for measuring magnetic force
The measurement is performed using a standard gaussmeter at the point with the structurally highest magnetic induction - at the pole extensions or at the lowest point of the arc of the magnetic circuit. The test is repeated 3 times, each time at a different point of the magnetic circuit, and the average magnetic induction is calculated.
Procedure for measuring pull-off force
We measure using a polished steel standard with a diameter of 10 mm and a height of 20 mm. The measurement is performed at the point with the structurally highest pull-off force - at the pole extensions or at the lowest point of the arc of the magnetic circuit. We record the force at which the standard detached. The test is repeated 3 times and the average pull-off force is calculated.
For your information, 10 N = approx. 1 kg.
The resulting pull-off force depends on many factors - e.g. the dimensions of the standard, the air gap between the standard and the tested magnetic circuit, the surface finish of the standard, etc.
Main advantages
The test rod is equipped with a magnetic core with neodymium magnets. The core is enclosed in the rod and can be moved up and down as needed. The outer part of the rod is made of stainless steel (grade 1.4301/ AISI 304 – suitable for food industry use) with a polished surface finish. The handle of the magnetic rod is made of hard plastic for easy handling. As standard, the test rod can be used in thermal conditions up to a maximum of 80 °C. We do not recommend exceeding this temperature, as gradual demagnetization may occur.
The magnetic test rod is easy to use. It is inserted into a container with the mixture and the presence of metal and magnetic impurities is tested by circular movements. These are captured on the lower half of the rod. After removal from the container and pulling the plastic handle, the impurities easily fall off the surface of the rod on the lower half.
Key properties
The magnetic test rod with a length of 150 mm has a diameter of 26 mm. Inside there is a neodymium magnet with a pull-off force of 102 N, corresponding to a magnetic force of 12400 Gs. The weight is 1.1 kg.
WARNING: The stated pull-off force values of some products were measured under ideal conditions defined by the test environment. However, these values may vary depending on the specific type of environment, for example operating conditions and subsequent wear may affect the efficiency of the product. However, measurements were not carried out for all products, and in such cases these are only estimates or an internal auxiliary calculation by the seller. The stated values must therefore be considered indicative, and any deviations from them cannot be regarded as a defect within the meaning of the provisions of Section 2095 and Section 2161(1)(a) of the Civil Code. To determine the exact pull-off force value in a specific case, it is necessary to carry out your own measurement. If the determined pull-off force values are not sufficient for you because they will not correspond to the stated values, you may use the guaranteed option of returning the goods within 30 days under the conditions stated here: https://e-shop.magsy.cz/vraceni-zbozi/and purchase a stronger magnet. These 30 days serve precisely for testing the goods, and after this period the seller may refuse to accept the return.
