يجب التحقق دائمًا من الموازين أو المقاييس باستخدام الأوزان المرجعية التي يمكنك الاعتماد عليها والثقة بها. تقوم مختبرات الكتلة المعتمدة بتنظيف ومعايرة وضبط الأوزان لديك، ثم توثق النتائج في شهادات المعايرة بتفاصيل تصحيح الكتلة التقليدية ومعلومات اللايقين وقابلية التتبع وفقًا للمعيار ISO/IEC 17025.

Single Test Weights | Weight Sets | Reference Weights and Microgram Weights | CarePac® |
High-quality OIML and ASTM Weights protected in a robust and easy-to-clean plastic container. | Expertly manufactured OIML and ASTM Weight Sets supplied in a solid easy-to-clean aluminum or plastic case. | Weights for highest metrological performance and specialized applications. | Unique solution for convenient routing testing in OIML and ASTM Weights. |
Long-Life Test Weights The finest quality stainless steel offers the highest resistance to corrosion over a weight’s lifetime. Calibration Certificate Needed? Calibration certificates document that test weights are fit-for-purpose - requested e.g. by internal quality assurance, ISO 9001, FDA or GMP. Protection and Durability Robust and easy-to-clean plastic containers maintain test-weight integrity and accuracy. | Individual Weight Sets Choose the weight set you need from 1 mg up to 5 kg. Add calibration certificates to provide reassurance that measurements can be validated at any time. Protection and Longevity Robust, easy-to-clean aluminum (OIML E1-F1) or plastic (ASTM 1-4 and OIML F1-M1) cases protect the integrity of the weights. Marking Weights with Identical Values If two weights in the set have the same nominal value, they are marked differently. | Mass Standard Calibration We offer high-grade stainless steel knob and wire weights for weight calibrations and as reference weights in mass calibration services. “E0” Reference Weights Class "E0" weights (with a higher accuracy than OIML class E1 weights) enable calibration of mass standards at the highest metrological performance. Range: 0.05 mg up to 50 kg. Microgram Weights for Specialized Applications Microgram weights (50 µg to 500 µg) offer a test weight solution beyond traditional weighing boundaries. | Efficient Routine Testing A CarePac contains everything you need for efficient balance routine testing in accordance with USP chapter 41 and GWP®. Just Two Weights According to GWP® two test weights are sufficient: at 5% capacity (repeatability) and at 100% capacity (sensitivity and eccentricity) Comprehensive Solution CarePac sets are supplied with a calibration certificate and professional weight-handling accessories so routine tests can be performed without worry. |

Brochure: OIML and ASTM Weights
METTLER TOLEDO's world leading expertise in metrology extends to weights, weight sets and weight calibration services. The weight portfolio covers OIML and ASTM weights from fifty micrograms to five 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.

Guide: Routine Testing of Laboratory Balances
Consult this guide on how to perform balance routine testing correctly. Easy-to-follow material outlines how often to test, how to test and which weights to use to ensure proper balance function.

Tips & Tricks: 12 Practical Tips for Correct Weight Handling
Weights are the most frequently used and most important equipment for testing scales and balances. And as such, 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; and more.
