Balances or scales should always be checked with reference weights that you can rely on and trust. Our accredited mass laboratories clean, calibrate and adjust your weights, then document the results in calibration certificates with details of conventional mass correction, uncertainty and traceability information according to ISO/IEC 17025.

Industrial Weights
As with laboratory balances, industrial scales and weighing platforms are also subject to regulations that ensure measurements are reliable and meet legal requirements. Regular testing with adequate test weights is essential. METTLER TOLEDO’s grip-handle and heavy-capacity weights are suitable for any application in all types of industrial environments. Choose the weight that best suits your needs out of our wide range of stainless steel and coated cast-iron weights from a nominal value of 1kg up to 5000 kg.
OIML Weights
METTLER TOLEDO's world-leading expertise in metrology extends to weights, weight sets and weight calibration services. Our weight portfolio covers OIML weights from 0,05 mg to 5 tons in all accuracy classes. Our weights are used all over the world not only for testing balances but also as primary standards in mass laboratories.
Weights Competence
For our weights, we source only the finest quality austenitic steel which offers the highest resistance to corrosion over the course of a weight’s lifetime. Our unique manufacturing process involves melting the steel under vacuum, polishing it using traditional mechanical methods, performing an electrolytic final-stage polishing, cleaning it in a fully automated process and then calibrating it using state-of-the-art mass comparators. This process has been perfected over years of experience to bring you accurate weights of the highest quality with a stability that remains unmatched in the market.

12 Practical Tips for Correct Weight Handling
Weights are the most frequently used and important equipment for testing scales and balances. And as such, they need to be handled with care.
Read why:
- You should store weights near the balance
- You should not touch weights with bare hands
- You should not clean weights with certain chemicals
For these and other important suggestions that extend the usable life of your test weights and improve your ongoing weighing accuracy, simply register below to download your free copy of "Correct Weight Handling—12 Practical Tips"
