Verification of measuring instruments. Thermometers and scales must have a valid verification certificate. Without it, their readings are not legally valid.

WeSetup automatically calculates the next verification date and attaches a scanned certificate.

The same file the service provides to an inspector. The data is fictional: the organization “Ромашка” and five employees.
