 What is the OIML Calibration Weight Set?

OIML weight sets are a complete set of calibrated test weights that can meet the requirements for testing to OIML standards. E1 calibration weights offer the highest accuracy required for advanced precision and analytical balance calibration. F1 Weights offer mid-range accuracy and are typically used to calibrate precision balances. M1 weights offer the lowest accuracy but are more affordable and are ideal for calibrating compact balances and bench scales.

What are the features of our OIML Calibration Weight Sets?

Our test weight sets feature individual calibration weights constructed from polished stainless steel for long term stability and are supplied in an aluminium case complete with gloves, and tweezers for handling the smallest weights. All our weights are checked and tested to make sure that they are within the relevant class tolerance levels.

Applications of the OIML Calibration Weight Sets

Our OIML Calibration Weight Sets are perfect for guaranteeing the accuracy of your scale or balance. Calibration certificates traceable to National Standards or full UKAS calibration certificates are available. Find the perfect size calibration test weight for your needs with our wide range of options.
