Functions and use
The testo 6621 is a transmitter for relative humidity and temperature. In the A01
(wall/voltage output) (see identification plate), the sensors are located in the
housing; in the A02 (duct) version and the version A03 (wall/current output), the
sensors are located in a permanently connected probe shaft. The transmitter is
available with an integrated display for the reading as an option (cannot be
retrofitted by the customer).
Applications include: Air conditioning, particularly in air conditioning in buildings
and during storage. The product is not suitable for high-humidity drying
processes (relative humidity constantly over 90 %).
The transmitters must only be assembled, wired and connected by qualified
personnel.
The product must not be used in areas at risk of explosion!
