The industrial humidity transmitter - testo 6681 - 1

testo 6681 + Probe series testo 661 x The industrial humidity transmitter Digital, exchangeable probes for specific applications: testo 6611 : Indoor air probes for wall mountinge testo 6612: Process climate probes for duct testo 6613: Process humidity probes as duct versionse testo 6614: Humidity probes for high humidity testo 6615: Trace humidity probe with self-adjustment testo 6617: Humidity probe with self-monitoring for sensor-damaging media. testo 6681 + Probe series testo 661 x Industrial humidity measurement demands absolute professionalism. Not only in running the system, but also in the measuring technology used. The industrial humidity transmitter testo 6681, combined with the probe series testo 661 x fulfils these high demands. The testo 6681 has a number of additional features, above and beyond the properties and benefits of a conventional transmitter, which will delight practitioners. Stationary humidity measurement in production/process technology: • Drying processes: - Drying tobacco, - Ceramics production - Drying roof tiles • Spray-painting booths - Maturing cheese - Ripening fruit - Drying pasta • Mushroom farming • Special areas high humidity Stationary measurement of indoor ambient • Monitoring comfort levels • Storage of hygroscopic substances • Storage of electronic components Optimum adjustment concept thanks to adjustment of the entire signal chain incl. analog Profibus, Ethernet, relay and analog outputs allow optimum integration into individual automation Self-monitoring and early warning guarantee high system availability Calculation and presentation of all relelvant humidity parameters P2A software for parameterization, adjustment and analysis saves time and costs in commissioning Display with multi-language display Robust, easy-to-clean metal housing Probe series testo 661 x Testo humidity sensor guarantees highest long-term
