The requirements for humidity measurement vary no matter whether it involves air velocity & IAQ measurement or the cold chain, industrial moisture measurement, or cleanrooms.

Depending on the measuring task, either a conventional humidity meter or a complex system that handles critical applications effortlessly and reliably is the right one for you. So, the ideal humidity meter does not have to outclass absolutely every other one in technical terms. It needs to provide you with optimum support for your specific task:

• Comfort level: Comfort level is an important parameter for setting heating and ventilation systems. Relative humidity and temperature are the crucial parameters for monitoring the thermal comfort level. In this respect, relative indoor humidity should range between 30% and 65%.
• Mould detection: Mould is not always a consequence of structural damage, but can occur due to incorrect ventilation behaviour. Handy thermohygrometers or thermal imagers with a special humidity image measuring mode are suitable for mould measurement. With a humidity meter which calculates the dewpoint, you can also locate susceptible areas where there is a risk of condensation.
• Long-term measurement: Where archiving, storage or comfort level are involved, humidity measurement over longer periods of time is of major importance. A Testo humidity data logger is ideal for long-term data measurement. This allows effortless handling of the high-precision, long-term measurement and documentation of air humidity values.
• Material moisture: A Testo material moisture meter is very practical in terms of controlling storage and drying conditions. It measures the moisture of building materials and timber in a non-destructive way using thin, high-performance penetration needles. Special models also enable air humidity measurement. You can thus detect the causes quickly and thoroughly when humidity levels are too high.
