When is humidity measurement useful?

Add a humidity channel when its result will change a real product or condensation decision.

Short answer

First identify which decision humidity data could change: a product condition, a drying or weight-loss investigation, or condensation review. Confirm the target against product and packaging instructions, then place the sensor for the area it must represent. Do not treat relative humidity as a direct measurement of water inside the product.

A second sensor channel is useful only when humidity results will affect a decision defined in advance.

Is the product exposed or packaged, and is the question product loss, surface drying or condensation? If manufacturer conditions or the site's quality plan do not support the measurement, do not add a channel simply to collect more data.

Specify in the test plan where the sensor should represent air humidity and assess it separately from the temperature sensor. One reading beside the load may not describe the condition of the whole container or product.

Review temperature and relative humidity on the same timeline with door events and product inspection notes. If condensation appears, record its location, surface and conditions with a photo; consult validated instructions for product decisions.
