Description: The latest generation of our humidity/temperature transducer offers even greater
possibilities to compensate the special sensor characteristics due to the
brand-new
microprocessor technology. Regarding precision, temperature stability and
functionality a new dimension has been reached. The transducer can be used for almost all
applications due to the different types (e.g. wall or channel mount, with
separated probe or with heat absorption hat) and the wide temperature range (electronic:
-25°C..+50°C; sensor: -40..+120°C).
