Air humidity has a crucial influence in terms of how well or unwell people in a room feel. The ideal ambient humidity is between 30 and 65% RH. In addition, temperature is also of course crucial. As you certainly know: high humidity can be extremely stressful at correspondingly high temperatures. You soon feel as if you were in the jungle.
That is why a Testo moisture meter is generally fitted with humidity and temperature sensors. This means you can always keep an eye on the two corresponding values. Depending on the model, your moisture meter can also calculate and show the dewpoint temperature based on these values. This is in turn crucial in terms of assessing areas in a room that are susceptible to mould.
