The Testo 6740 trace humidity sensor monitors moisture levels in air and compressed gasses. The Testo 6740 two-wire unit provides a scalable 4-20mA output signal and can be ordered with or without a local display. Calibrated to ±1% relative humidity and long-term sensor stability makes the 6740 ideal for monitoring compressed air dryers and preventing system damage from condensing water vapor.

The Testo 6740 trace humidity sensor can be configured for a variety of applications. An optional connecting plug can be added to the Testo 6740 to provide 2 limit signal alarms with LED status outputs to ensure your process is within tolerance. The sensor can be installed directly in-line or combined with measuring chamber and cooling coils to suit specific application.

The Testo 6740 housing rotates 350° and can be ordered with a ½" NPT or G1/2 process connection for ease of installation. The Testo 6740 is a simple, flexible, and cost effective sensor for trace humidity monitoring.
