The transmitter testo 6781 was developed specially for trace humidity measurement in compressed air and in dry air (e. g. in granulate dryers). The international norm ISO 8573 categorizes seven classes of compressed air. High-performance adsorption dryers are required in order to meet the highest quality classes 1 and 2. They can be monitored by the testo 6781 down to very low dewpoints of -90 °Ctd.

The newly developed sensor with sol-gel technology is characterized by its condensation-proofness and fast response time, thus guaranteeing highest process security.

Areas of application:

Dewpoint measurement in compressed air in ISO Classes 1 (-70 °Ctd ) and 2 (-40 °Ctd)
Monitoring of adsorption dryers, granulate dryers and medical compressed air
Quality assurance for noble gas preparation
