testo 6740

nnnn

The testo 6740 was especially developed for trace

nnnn

humidity measurement in compressed or dry air (e.

nnnn

g. granulate dryers). Thanks to a special adjustment,

nnnn

optimum accuracy in the trace humidity range has

nnnn

been achieved. The result of the development of the

nnnn

testo 6740 is a measuring range of -45 °Ctd to

nnnn

+30 °Ctd and excellent accuracy.

nnnn

For the display of the relevant trace humidity

nnnn

parameters, a freely scalable analog output is

nnnn

available, optionally with a switch contact plug for

nnnn

MAX monitoring. In addition to this, the testo 6740

nnnn

stands out thanks to its compact and user-friendly

nnnn

design, such as the rotatability of the housing by

nnnn

350° for the optimum positioning of the display.
