Testo 6681 Offers

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).

Features

  • Optimum adjustment concept thanks to adjustability of the entire signal chain incl. analog adjustment
  • Analog outputs enable optimum integration into individual automation systems
  • Calculation and presentation of all relevant humidity parameters
  • Self-monitoring and an early warning function ensure high system availability
  • 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

Applications

  • Drying processes (e.g. drying tobacco, manufacturing ceramics, drying roofing tiles)
  • Painting installations
  • Food production (e.g. cheese processing, ripening fruit, drying pasta)
  • Storing electronic components
  • High-humidity specialist fields
  • Sterilization processes in an H2O2 environment
  • Bio research
  • Mushroom cultivation
  • Clean rooms
  • Museums
