nnnn

The transmitter testo 6781 was developed specially

nnnn

for trace humidity measurement in compressed air

nnnn

and in dry air (e. g. in granulate dryers). The

nnnn

international norm ISO 8573 categorizes seven

nnnn

|k classes of compressed air. High-performance

nnnn

/ fclO/y-e"! ^ adsorption dryers are required in order to meet the

nnnn

highest quality classes 1 and 2. They can be

nnnn

monitored by the testo 6781 down to very low

nnnn

dewpoints of -90 °Ctd.

nnnn

The newly developed sensor with sol-gel technology

nnnn

is characterized by its condensation-proofness and

nnnn

fast response time, thus guaranteeing highest

nnnn

process security.
