Product Description

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

Technical highlights of the testo 6681 climate transmitter

  • High-quality digital probes available for the temperature/humidity transmitter: e.g. high-precision Testo humidity sensor with long-term stability, probe for high-humidity measurement, probe for trace humidity measurement, probe with a self-monitoring function (for measuring in sensor-damaging media)
  • Smart probe technology: probe can be changed by the user, digital interface for the temperature/humidity transmitter, intelligent calibration concept
  • Ethernet, relay and analog outputs allow for versatile use of the temperature/humidity transmitter: e.g. for control purposes (2 or optionally 3 analog outputs), for direct activation of units in the air conditioning system (optionally via relay) or even in climate monitoring systems (optionally via Ethernet connection)
  • P2A software for parametrization, adjustment and analysis saves time and money during commissioning and maintenance
  • Optimum protection: the temperature/humidity transmitter features a robust metal housing and is protected against water jets according to protection class IP 65. Protective caps are also optionally available for specific applications (made of stainless steel, PTFE, wire mesh filter or metal). A patented H2O2 protective cap is also available to order
  • 2-line display: the climate transmitter is optionally available with a display, enabling you to undertake commissioning, adjustment and analysis without using a PC
  • Options for self-monitoring and early warning function: guarantees high system availability
In combination with the right probe, the testo 6681 temperature and humidity transmitter offers superior properties and benefits in comparison with a conventional climate transmitter because, when it comes to humidity measurement, this instrument features unrivalled, cutting-edge technology.

Note: Please note that the transmitter can only be operated with a probe. The probes are optionally available.
