Precision & Accuracy
Test weights are indispensable tools for maintaining/checking precision and accuracy in weighing instruments, ensuring the integrity of processes and compliance with quality standards. With our comprehensive range of test weights and expert support, you can trust us to provide test weight solutions tailored to your specific requirements.
M1 Class
Accuracy: M1 class test weights provide a lower level of accuracy compared to E2 and F1 class weights. They have wider tolerances but still offer accuracy for general calibration and verification purposes.
Application: M1 class test weights are commonly used for routine calibration of industrial scales, platform scales, and weighing systems where high precision is not critical.
F1 Class
Accuracy: F1 class test weights offer high accuracy but with slightly looser tolerances compared to M1 class weights. They are suitable for calibrating analytical and precision balances in laboratory and industrial settings.
Application: F1 class test weights are widely used in quality control laboratories, manufacturing facilities, and calibration laboratories where precise measurements are essential.
E2 Class
Accuracy: E2 class test weights are designed to meet the highest level of accuracy standards. They have extremely tight tolerances and are suitable for calibrating laboratory balances and precision scales requiring the utmost precision.
Application: E2 class test weights are commonly used in research laboratories, pharmaceutical industries, and other environments where precision weighing is critical.
When selecting test weights for calibration and verification, it's essential to choose the appropriate class or accuracy level based on the specific requirements of your weighing instruments and applications. Using test weights with the correct accuracy class ensures accurate and reliable measurements, helping maintain the integrity of your weighing processes.
Traceability and Compliance
Certified test weights are traceable to national or international standards, providing assurance of their accuracy and reliability.
Compliance with regulatory requirements and industry standards often mandates the use of certified test weights for calibration and verification purposes.
Accuracy Classes
Test weights are classified into different accuracy classes (e.g., M1, F1, E1) based on their precision and tolerance levels.
The appropriate accuracy class of test weights depends on the application and accuracy requirements of the weighing instrument being calibrated.
Material and Construction
Test weights are typically made from materials such as stainless steel, brass, or cast iron, chosen for their stability, durability, and resistance to corrosion.
Precision machining and careful construction ensure that test weights maintain their accuracy and stability over time.
Expert Guidance
Our expert team can assist you in selecting the right test weights and providing guidance on calibration procedures to ensure accurate and reliable measurements.
We are also able to provide a calibration and certification service for any existing weights you may have that require annual calibration to meet your quality standards. Please note however it is not possible to carry out calibration and certification of test weights on site.
