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. Optimum adjustment concept thanks to adjustment of the entire signal chain incl. analog adjustment 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 absolute humidity and dewpoint. P2A software for parameterization, adjustment and analysis saves time and costs in commissioning and maintenance
Display with multi-language display. High-quality plastic housing.
testo 6651 temperature/humidity transmitter for critical climate applications with selectable signal outputs, optional display, optional Ethernet module and optional relay (depending on the configuration).
