We provide on-site calibration for all major brands of Precision, Analytical, Semi-micro, Micro and Ultra Micro Balances.

Calibration is always performed using OIML Class E weights certified by National Metrology Centre. By using the finest quality weight sets, we ensure calibration of your balances is performed using weights of class tolerance factor equal to or better than that recommended by the balance manufacturers.

To maintain the lowest possible measurement uncertainty for our weight sets, we calibrate them periodically and monitor the mass stability of all our weights in use. Any weights found defective at the time of re-calibration or subsequent verification are retired and replaced with new weights.

Prior to performing any calibration tests, we ensure our weights are acclimated to the ambient conditions of your laboratory. Corresponding changes in air density can affect the accuracy of our measurements and therefore, buoyancy correction is always performed for balances under test with readability equal to or better than 0.01mg.

Our site calibration team is also trained to identify potential issues that may affect the performance of your weighing balances. Where required or requested to, our site calibration engineer will help to identify the best places to re-locate your weighing balances and assist with any recommendations for any remedial actions needed to be carried out to improve the weighing performance of your balances.
