A calibrated (certified) scale is a scale suitable for trade purposes - for example, when a price is calculated based on weight, such as a greengrocer charging a price per kilo.
A calibrated scale can be recognized by a metrological mark and seals, which ensure that the scale cannot simply be recalibrated or adjusted by the user.
A calibrated scale also always has a fixed division: for example, a 3 kg scale can be certified to an accuracy of 1 gram, but not half a gram - this is set by law.
A calibrated scale is not the same as a calibrated-for-accuracy (adjusted) scale: adjustment only involves resetting and checking the scale using reference weights, without the official certification and sealing that comes with legal calibration.
Tegra Systems is itself accredited by Agentschap Telecom (now the Rijksinspectie Digitale Infrastructuur, RDI) to break and reapply the seals of calibrated scales, and also provides a digital measurement report recording the findings and accuracy of the scale.
We also offer an annual inspection of calibrated and non-calibrated scales upon request, so you can be sure all your scales continue to weigh accurately.
