Test Weights
Calibration weights in E2, F1, F2, M1 and M2 classes, from milligram laboratory sets to cast iron blocks for weighbridge testing.
What This Category Is For
A scale is only as trustworthy as the weights used to check it. We manufacture weights across the full class range, in stainless steel, chrome plated steel and cast iron, so a laboratory set and a pallet of weighbridge blocks can ship on the same order as the scales they verify.
Problems It Solves
- Scales drifting between annual verification visits with no way to check them in house
- Laboratory balances checked with weights of the wrong class
- Weighbridge tests delayed while heavy test weights are hired
Every Test Weight Model We Supply

Stainless Steel Cylindrical Test Weight Set
Cylindrical calibration weight sets in stainless steel and chrome plated finishes, E2 to M2.

Cast Iron Block Test Weights
Cast iron block weights with cut out handles for floor scale and weighbridge verification.
View specifications →Who Buys This Category
- Quality laboratories checking analytical and precision balances
- Scale service companies carrying a calibration kit
- Factories that verify their own platform and floor scales
- Weighbridge operators running periodic accuracy checks
Core Advantages
- Full class range from E2 down to M2 on one order
- Stainless steel, chrome plated and cast iron construction
- Small cylindrical sets for balances and heavy blocks for industrial scales
- Ships with the scales they are meant to verify
Typical Application Scenarios
Daily check of an analytical balance with an E2 or F1 set
Verifying a 300 kg platform scale after relocation
Loading cast iron blocks onto a weighbridge deck for a linearity test
Where These Models Are Used
Laboratory And Quality Control
A quality laboratory has two weighing problems: reading finely enough to prove the tolerance, and proving the balance itself is still right.
Scale Manufacturing And OEM
Scale builders do not buy products, they buy tolerances. What matters is whether the cell can carry the division count you sold, whether the head will pass the same approval, and whether the second batch matches the first.
Logistics And Warehousing
Logistics weighing is about evidence. Every pallet, every vehicle and every lift has to leave a number that someone else will accept later.
Test Weights Questions
Which weight class should I buy?
Match the class to the scale. E2 and F1 sets are used for analytical and precision balances, F2 and M1 for bench and platform scales, and M1 or M2 cast iron blocks for floor scales and weighbridges. Tell us the scale readability and we will confirm the class.
What materials do you supply?
Stainless steel, chrome plated steel and cast iron, depending on class and size. Laboratory classes are supplied in stainless steel, and heavy industrial blocks in cast iron.
Do the weights come with a calibration certificate?
Tell us at order stage whether you need a certificate issued with the weights and which class it must cover, and we will confirm what can be supplied for the exact size you order.
Specify Your Test Weight With Us
Send the capacity, division, protection rating and destination market. We will confirm the model, the approval documents and the freight before you commit.
