M1 level lock standard weight (according to national standard requirements)
Our company is a manufacturer specializing in the production of standard weights, direct supply, no intermediate links, and obvious price advantages. The standard weights provided by our company have a favorable price and quality assurance. Standard weight products are sold to South Korea, Japan, and European and American markets. The production capacity is more than 10,000 tons. If you have any questions about the price, manufacturer, model, and pictures of standard weights, please contact us for new information on counterweight irons.
Introduction to weight measurement——
In modern mass measurement, the weight is the standard measuring tool for the transmission of the mass value. The mass value is based on the original platinum-iridium alloy kilogram stored in the French International Bureau of Weights and Measures, so its accuracy is particularly important. Accurate weighing results are very important to all walks of life, especially in pharmaceutical and biotechnology industries that are regulated by the government. Although conventional balance testing can improve safety and measurement accuracy, we recommend In some important control process areas, the balance needs to be calibrated more deeply.
Weight verification standard——
The procedure is applicable to accuracy grades of E (subscript 1), E (subscript 2), F (subscript 1), F (subscript 2), M (subscript 1), M (subscript 1) Standard 12) grade, M (subscript 2) grade, M (subscript 23) grade, M (subscript 3) grade of 1mg to 5000kg weights. The weights of each accuracy level should be equipped with corresponding measuring instruments for use. It can be used to verify weights and measuring instruments with lower accuracy levels. In actual use of the procedure, the nominal value of the weight can be expanded up and down within the corresponding accuracy level as required.
This regulation is applicable to the first verification of various weights (the verification after repair is regarded as the first verification, the same below) and subsequent verification.
Classification of weights——
1. According to the new weight verification regulation JJG99-2006
2. The weights are divided into grades: 9 grades: E1, E2, F1, F2, M1, M12, M2, M23, and M3.
3. The grade is divided according to the uncertainty, that is, the equal weight has a correction value, and the grade is divided according to the indication error, that is, the grade weight has no correction value. As long as the indication error is within this range, it is considered qualified!
4. You can choose the balance that suits your needs. Weight performance parameter standard
5. The weight, volume, thickness, color, price, etc., are good for you, and Shirun will help you make smart purchase choices.
Magnetic susceptibility of weight——
·Metal weights are more or less magnetic due to the ratio of materials.
·The weights with magnetism will inevitably cause certain errors in the weighing and affect the accuracy of weighing.
·So the lower the magnetic susceptibility of the weight, the higher the accuracy of weighing.
Weight material density-
·The density of weights (g/cm3) that need to be applied to certain specific weighings.
·For example, to measure the density of a liquid, according to Archimedes’ principle, when the object is completely immersed in the liquid
·Requires that the volume of the object is equal to the volume of the replacement liquid.
· Know the volume of the weight, and then easily measure the density of the liquid according to ρfl=(ρs×mfl)/ms or ρfl=mfl/Vs.
M1 lock standard weights (according to the requirements of the national standard) · E2, F1, F2, M1 stainless steel weights 50g-2kg comes with a plastic box; less than 50g due to the volume limitation, only a plastic bag with a pull-out;
·Steel chrome-plated weights are not delivered in a box regardless of their specifications. If necessary, they can be purchased separately. Our store also has a separate box for sale;
·Because the custom-made weights are different from the conventional shape, they are not equipped with boxes at the factory;
·The production of weights is in the form of 1, 2, 2, 5
·For example, 1g-50g boxed weights have specifications: 1g, 2g, 2g, 5g, 10g, 20g, 20g, 50g, a total of 8 weights.
·The reason for this formulation is that 3g, 4g, 6g, 7g, 8g and other weights can be obtained by adding the above conventional weights.
·Cylindrical weights, hook weights, lock weights, square weights, pie weights, double hook weights, brass weights
·The weights are divided into benchmarks and various grades of standard weights
·At present, our country has been in line with the international metrology organization, using the kilogram system kg
