M1 grade 1g-25kg stainless steel material standard weight manufacturer in stock

The main types of weights include stainless steel weights, standard weights, cast iron weights, balance weights, electronic scale weights, incremental weights, Newton weights, hook weights, etc

Balance weight: material type- Non magnetic stainless steel Non magnetic stainless steel, copper chrome plated, iron chrome plated.

Weight shape- Garden pillar Garden cone Plate shape Sheet shape Ring shaped Riding form Bar shaped

combined form- Conventional combination 5.2.2.1, (can be combined arbitrarily according to user needs)

accuracy class- First class (E2). Second class (F1 actual difference) F1 (Level 3 tolerance) F2 (Level 4) M1 (Level 5) M2 (Level 6)

Weight usage tip: Before using the weight, use a specialized cleaning brush and wiping cloth to remove dust and other stains from the surface of the weight. It is strictly prohibited to touch weights directly with hands. When using weights, please wear specialized gloves and use specialized tools to clamp the weights. Before conducting balance testing or weight comparison, the weights need to be kept at a constant temperature to achieve the atmospheric conditions of the laboratory, otherwise it will affect the test results. After use, the weights must be stored in the original packaging box

A weight is a standard weighing device and a type of weight. How to avoid damaging weights during transportation?

Shanghai Tingheng Industrial Co., Ltd. is a manufacturer specializing in the production of weights. Our weights have a strict packaging control process during the transportation process. Our high-precision weights (non-magnetic stainless steel weights, stainless steel weights, copper weights, steel chrome plated weights) should be put into a special weight foam box in the warehouse before shipment, and then put into a special paper box for packaging, with packaging tape. In order to send the weights to our users without any damage!

1. E1 level, E2 level, F1 level weights

The E1, E2, and F1 grade weights ranging from 1mg to 50kg should be solid integral structures composed of a single piece of material without adjustment chambers.

greater than50kg E2 and F1 grade weights can have an adjustment chamber. The volume of the E2 level weight adjustment chamber should not exceed 1/1000 of the total volume of the weight. F1 grade weights shall not exceed 1/20. The adjustment chamber should be sealed, waterproof, and gas resistant. Bolts, knobs, or similar components with ribbed patterns can close the adjustment chamber, and their material should be the same as the weight material. Their surface condition should meet the requirements of E2 grade and F1 grade weights.

After the first adjustment, the total volume of the adjustment chamber is about1/2 should be empty.

2. F2 grade weight

F2 grade weights ranging from 1g to 50kg have adjustment chambers, and their volume should not exceed 1/4 of the total weight volume. Adjust the chamber and seal it with a knob or other means.

After the first adjustment, the total volume of the adjustment chamber is about1/2 should be empty.

greater thanThe 50kg F2 grade weight can be made of multiple materials and needs to be sealed with waterproof or dustproof welding. The weight can be composed of various materials, and its magnetism should meet the requirements of F2 grade weight. There is an adjustment chamber, and the volume of the adjustment chamber should not exceed 1/20 of the total volume. The adjustment chamber should be sealed, waterproof, and gas resistant. Ribbed bolts, knobs, or similar components can enclose the adjustment chamber.

After the first adjustment, the total volume of the adjustment chamber is about1/2 should be empty.

3. M1 level, M12 level, M2 level, M23 level, M3 level

There is no mandatory regulation on whether M1, M2, M3 grade weights from 1g to 50kg have adjustment chambers. There is no mandatory regulation on whether M1, M2, M3 grade weights from 100g to 50kg have adjustment chambers. M1, M2, M3 grade weights from 100g to 50kg should have adjustment chambers. The adjustment chamber should have a reliable chamber cover to prevent external substances from entering. Allow the adjustment chamber to be opened and the adjustment material to be added. The volume of the adjustment chamber should not exceed 1/4 of the total volume of the weight.

After the first adjustment, the total volume of the adjustment chamber is about1/3 should be empty.

For M1, M2, and M3 cylindrical weights ranging from 1g to 50kg, adjust the chamber to be coaxial with the vertical axis of the weight, open above the weight knob, and widen the inlet diameter. Adjust the design of the cavity to ensure Puma sealing and easy opening.

Parallel hexahedral weights of M1, M2, and M3 grades ranging from 5kg to 50kg can have their adjustment chamber located inside the tube or, if the lifting knob is solid, directly above the weight with an opening on the side or upper surface of the weight.

If the adjustment chamber is inside the tubular knob, it can be closed with a threaded plug or a disc cover with a central knob. The plug or disc cover can be made of copper alloy or other suitable metal material and should be sealed by inserting a lead plug into the internal screw hole or strip tube.

If the adjustment chamber is cast above and the opening is on the side or upper surface of the weight, the adjustment chamber should be closed by a disc made of soft steel or other suitable material, sealed by a lead plug or appropriate material introduced into the conical hole.

greater than50kg M1 grade, M12 grade, M2 grade, M23 grade, M3 grade weights should not have any cavities that cause dust accumulation.

The weight can have one or more adjustment chambers, and the total volume of all adjustment chambers should not exceed the total volume of the weight1/10. The cavity should be sealed, waterproof, and dustproof. The adjustment chamber can be sealed with a threaded plug or knob.

After the first adjustment, at least1/3 of the volume is empty.
