Fourth class cast iron weights, large quality standard cast iron weights ranging from 5KG to 2000KG, as well as various special-shaped standard cast iron weights

Cast iron weights include M1 and M2, ranging from 1kg, 2kg, 5kg, 10kg, 20kg, 25kg, 50kg, 100kg, 500kg, and 1000kg

Characteristics of cast iron weights: Beautiful appearance, smooth surface, accurate measurement, easy to use, and can be designed and manufactured in various specifications and shapes according to user needs

Cast iron weight material: secondary modified casting of raw iron. The surface is polished to a very smooth finish and coated with black paint. Non steel ladle iron (steel slag)

Due to the weight of the weight, the shipping cost should be calculated based on the actual shipping address.

It can be said that if there are no weights in the scale, then the scale and various scales cannot function properly. To explain the term weights accurately and clearly, the important role of weights is to determine whether they can work properly.

① How to choose standard weights

The selected standard weight can be a grade weight or an equal weight, but its error (mass tolerance for grade weights and verification accuracy for equal weights) must not exceed 13% of the maximum allowable error of the verified balance under that load; Secondly, the range of standard weights can cover the large weighing range of electronic scales.

② Exemption from inspection of standard weights

(1) When d ≤ 1mg, an electronic balance can be exempted from testing its discriminatory power

(2) When e ≠ d, an electronic balance is exempt from checking its discriminatory power

(3) For scales with digital indicators and automatic or semi-automatic calibration devices, the sensitivity of the balance can be exempted from inspection

③ The issuance of verification certificates should be standardized

After the calibration of standard weights is completed, a calibration certificate or calibration result notification should be issued based on the actual calibration results.
