Relative Humidity

Loggers that record relative humidity, nearly always together with temperature and, in several models, dew point. They are used to prove storage and transport conditions, follow offices, schools and greenhouses and log conditions at weather stations.

There are USB loggers with a display, Wi-Fi and wireless models linked to the cloud, single-use GSM loggers that travel with the goods, miniature loggers and a compact logger that calculates mean kinetic temperature (MKT), with optional FDA 21 CFR Part 11 software.
