Optimum adjustment concept thanks to adjustability of the

entire signal chain incl. analog adjustment

Ethernet, relay and analog outputs allow optimum

integration into individual automation systems

Self-monitoring and early warning guarantee high system

availability

Calculation and presentation of all relevant humidity

parameters

P2A software for parameterization, adjustment and analysis

saves time and costs in commissioning and maintenance

Display with multi-language display

Robust, easy-to-clean metal housing

The industrial humidity

transmitter

testo 6681 + probe

series testo 661x

Industrial humidity measurement demands absolute

professionalism. Not only in running the system, but also

in the measuring technology used. The industrial humidity

transmitter testo 6681, combined with the probe series

testo 661x fulfils these high demands. The testo 6681

has a number of additional features, above and beyond

the properties and benefits of a conventional transmitter,

which will delight practitioners. This and other reasons

make the testo 6681 the first choice in drying technology,

trace humidity and compressed air process technology, as

well as in demanding air conditioning technology, e.g. in

cleanrooms.
