PEL has researched together with leading conservators, curators and librarians to design and produce this thermohygrometer. The manufacturer is a worldwide respected company in the field of temperature and humidity measurement with strong research and development experience. We would not put the PEL logo on the meter unless we were completely satisfied that the technology was of the highest standard.

The meter can be switched off to save battery life with the level displayed, data logging mode is also shown. The actual RH and Temperature are displayed, changing from one to the other every 5 seconds.

Customers already using Tinytag data loggers can use the existing software and cable to activate the meter’s data logging. Alternatively if you are new to Tinytag, additional new data loggers can use the same software and cable.
