Humidity transmitter for critical climate applications - testo 6651 - 1

Humidity transmitter for critical climate applications Optimum adjustment concept thanks to adjustment of the entire signal chain incl. analog Ethernet, relay and analog outputs allow optimum integration into individual automation systems Self-monitoring and early warning guarantee high system availability Calculation and presentation of the humidity parameters "relative humidity" and "dewpoint". P2A software for parameterization, adjustment and analysis saves time and costs in commissioning Display with multi-language display High-quality plastic housing Probe series testo 660x Testo humidity sensor guarantees highest long- term stability and accuracy up to ±1.7 %RH Digital, exchangeable probes for specific applications: testo 6601: Indoor air probes for wall mounting testo 6602: Air conditioning probes for duct testo 6603: Process climate probes for duct testo 6604: Ambient condition probes as cable testo 6605: Process climate probes as cable versions (stainless steel probes up to 120 °C) testo 6651 + Probe series testo 660x Not all measurement problems can be solved with "simple" transmitters. The testo 6651 meets special challenges. When combined with the probe series testo 660x, the testo 6651 becomes the first choice in demanding air conditioning technology as well as in many other applications. Stationary measurement of indoor ambient conditions • Monitoring comfort levels Storage of hygroscopic substances Storage of electronic components Stationary measurement of production conditions • Drying processes / high humidity processes - Maturing cheese - Ripening fruit - Drying pasta - Conditioning chambers for sausage products Mushroom farming
