Everyone who has used cast iron weights knows that they need to undergo metrological verification before being reused. Let's see why cast iron weights can only be used after verification?

Why use certified calibration weights:

0 and * * OIML "E0" and "E1" are mainly used for * * accuracy, such as weight standards (calibration of other weights), microbalance testing and calibration, and important weighing applications.

Classes 1 and 2 and OIML E2 and F1 are used for precision applications, i.e. Analytical balance testing and calibration.

Levels 3 and 4, as well as OIML F1 and F2, are suitable for routine balance calibration and testing, as well as medium precision applications (non critical applications in the laboratory).

Note: If the balance or electronic scale has been calibrated, * * the weight setting and level used must be recorded.

Stainless steel weights have long-term stability. All weights are made of * * stainless steel, so * * can resist * *. After adopting the * * design, solid weights can maintain long-term stability, and weights with adjustable cavities have a higher cost-effectiveness. Electrolytic polishing technology ensures a bright surface and effectively prevents adsorption.

Maintenance of weights of different levels

1. All weights should be used in accordance with the regulations of the calibration system table. The first and second level weights use actual mass, while the weights at all levels use nominal mass.

2. Temporarily unused weights * * should be placed in a stainless steel weight box, and these weights should be placed in a clean, dry room or in a glass drying tray without temperature fluctuations.

3. Grade II and above Grade A weight should not be used with bare hands. Soft and clean deer skin, silk cloth, or fine yarn gloves should be used for use. The weight * * should be handled with care. When lifting large weights, they should be handled smoothly, slowly, and gently, without damaging or scratching the surface of the weights. If the surface of the weight is rusted, the coating peels off, or there are deep and long scratches, * * should be stopped from use and inspected again after repair.

4. The surface of the weight should be kept clean. Weights above level 4 should be cleaned regularly.
