The testo 6681 temperature and humidity transmitter is ideal for monitoring critical climate values in industrial processes or in research. The transmitter is designed for use in industry and is a reliable partner in trace humidity and compressed air process technology, drying and air conditioning technology.
Areas of application for the testo 6681 temperature and humidity transmitter
- Drying processes (e.g. drying tobacco, drying ceramics)
- Painting installations
- Food production (e.g. cheese processing, ripening fruit, drying pasta, mushroom cultivation)
- Bio research
- High-humidity applications
- Sterilization processes in an H2O2 environment
- Cleanrooms
Technical highlights of the testo 6681 climate transmitter
- Maximum measuring accuracy up to ±(1.0 + 0.007 x reading)
- Reliable and long-term stable humidity sensor
- Ethernet*, relay and analog outputs allow for versatile use, e.g. for control purposes (optionally 2 or 3 analog outputs), for direct activation of air-conditioning units (optionally via relay) or even in indoor climate monitoring systems (optionally via Ethernet connection)
- Options for self-monitoring and early warning ensure a high level of system availability
- Robust metal housing and water jet protection according to IP65
- Optional 2-line display enables commissioning, adjustment and analysis without using a PC
Enjoy all the benefits with the practical accessories
- Wide range of high-quality digital probes available: To commission the transmitter, you need a connectable probe. Use, for example, probes for high humidity or trace humidity measurement, probes for aggressive media
- Smart probe technology: Easy probe replacement, digital interface to the transmitter, intelligent calibration concept
- Optional protective probe caps available for special applications (made of stainless steel, PTFE, wire mesh filter, metal, or a patented H2O2 protective cap)
- Quick and easy commissioning and maintenance using the P2A software for parametrization, adjustment and analysis
