Calibration Weight Set Class F1 1 Mg - 1 Kg for Balance Scale 25 Pcs Weights 304 Stainless Steel High Precision

Specification: Class F1 Magnetic Susceptibility: ≤0.05; Density: 7.85g/cm3 Shape: Cylinder and Flake Material: 304 Stainless Steel Case Size: 9.1x5.7x4.3 inch / 23x14.5x11 cm Product Weight: 6.17 lbs / 2.8 kg Weight Range: 1mg-1kg Package: Aluminum Case 25PCS Weights Instructions for using weights: 1. The weights should be kept properly and should not be placed in a humid, dusty environment. 2. The weights in the box need to be counted before and after use to avoid loss. The plastic case is very helpful to store flake weights. 3. Do not directly touch the weight with bare hands. When using the weight, use a special tool to move the weight. 4. Before use, remove the dust on the surface of the weight with a soft brush or special wipe. 5. Handled with care and taken lightly. 6. The temperature of the weights should be the same as the temperature in the laboratory. About Calibration Weights: Calibration weights can be certified or uncertified. Certified weights meet strict guidelines for accuracy and can usually be recertified. They are used in labs where a high degree of accuracy and repeatability is required. Uncertified weights are used where a lower degree of accuracy is required, including student laboratories, rough weighting operations, and measuring force. The differences between Class F1 and Class M1 Weights: 1. F1 is more precise than M1, with smaller permission error. 2. F1 uses 304 stainless steel, M1 uses 2cr13 stainless steel. 3. M1 is with adjust bar (at the bottom of the weight), F1 is without. Package list: 25pcs weights 1 tweezer 1 cleaning cloth 1 aluminium alloy case 1 small plastic case

• Class F1 Calibration Weight Set-For calibrating other weights, or electronic balances and scales that with precision of 0.01-0.001g.
• 304 Stainless Steel-The material of the counterweight is 304 stainless steel. Stainless steel structure has stability, corrosion resistance and low magnetic susceptibility. The weights are solid.
