T 6651 & T 6681

• Sensors, Detectors and Transducers

Testo offers Humidity Transmitters. The models of Testo 6651 & 6681 are positioned in the middle to upper performance range. These are designed for the monitoring of critical climate in process engineering and also in compressed air technology. The demanding measurement is realized with the further developed Testo humidity sensor, with its well known and highly valued long term stability. Both instrument series present many innovations, including world firsts such as Profibus interface in the humidity transmitter’s Testo 6681 and an Ethernet interface in the humidity transmitters Testo 6681 and testo 6651.
