Inspection certificate 3.1 according to EN 10204

Sensors drift with mechanical, chemical and thermal stress, so the original accuracy can change over their life. A 3.1 inspection certificate documents the deviation of one sensor against a certified reference device at the time of testing. Each certificate is issued for the individual device in line with EN 10204 and lists the measured deviations. It confirms the sensor meets the accuracy in its datasheet at the time of manufacture or delivery. No adjustment or offset is applied to the sensor. There are three versions, for temperature, humidity and pressure, each with two measured values.
