How Often between Weight Calibrations?

You rely on your weights giving you accurate results with every measurement. Something as little as fingerprints from the operators hands can cause small discrepancy in your measurements.

How accurate your weights are depend on:

  • How often the weights are used
  • Skill of the technician using the weights
  • How the weights are stored
  • Weight Accuracy Class  
  • Finish of the weight


  • Our weight calibration experts are able to provide you with data based recommendations on calibration intervals. Most applications find the best success with weight calibration occurring every 6-24 months.
