Industrial humidity measurement requires absolute professionalism in measuring and control technology. In industrial processes or in research-based business, the testo 6681 temperature and humidity transmitter is ideal wherever critical climatic values need to be maintained. The climate transmitter boasts a high-precision humidity sensor with long-term stability (optionally available), which enables it to achieve maximum precision: up to ±(1.0 + 0.007 * reading). Precise measuring and control technology will help you to accurately optimize the climatic conditions in your rooms in order to prevent process disruptions and quality losses. Automation systems result in particularly efficient processes. The testo 6681 temperature and humidity transmitter can easily be integrated into individual automation systems because it features Ethernet, relay and analog outputs. Areas of application for the testo 6681 temperature and humidity transmitter Drying processes (e.g. drying tobacco, manufacturing ceramics, drying roofing tiles) Painting installations Food production (e.g. cheese processing, ripening fruit, drying pasta) Bio-research Breeding mushrooms High-humidity specialist fields Sterilization processes in an H2O2 environment Clean rooms Museums Storing hygroscopic substances Storing electronic components
