Weighbridge Calibration Frequency in Uganda – Smart Weighing Kampala

In Uganda, weighbridge calibration frequency is one of the most important factors that determine whether a weighbridge, axle load scale, or truck scale remains accurate, reliable, and legally compliant. Many businesses often ask:

• How often should a weighbridge be calibrated in Uganda?

• What does UNBS recommend for calibration frequency?

• What happens if I don’t calibrate my weighbridge regularly?

At Smart Weighing Kampala, we not only supply and install weighbridges but also provide professional calibration services in line with Uganda National Bureau of Standards (UNBS) regulations and international OIML guidelines.

What Is Weighbridge Calibration Frequency?

Weighbridge calibration frequency simply refers to how often a weighbridge should be checked and adjusted using certified calibration weights to ensure it provides accurate readings.

Calibration frequency is not fixed for every weighbridge; it depends on several factors such as:

• Volume of usage (daily truck loads)

• Type of industry (agriculture, transport, mining, construction, logistics)

• Environmental conditions (dust, humidity, uneven ground)

• Regulatory requirements (UNBS, trade compliance)

• Accuracy class of the weighbridge

To ensure accuracy, calibration must be performed using certified calibration weights in Uganda
