The testo 6651 is placed in the medium-high performance range. It is designed for the monitoring and control of sensitive environments in process engineering and for the control of compressed air systems.

Advantages of the testo 6651

• This new series of transmitters has interchangeable sensors, which are adapted to the application.
• The P2A adjustment and setting software gives you total control over the instrument.
• You can scale/calibrate/adjust the output signal on all outputs including the analog output.
• A further advantage is that the transmitter can be powered via USB.
• Adjustment or analysis can therefore be carried out without any other wiring – e.g. on the table or in the service workshop.
• Integrated relays (optional)
• Display (optional)

Using the optional display and the four buttons on the front, you can easily adjust, commission and analyze the instrument on site without a PC if you don’t have access to one.
Thanks to the new digital plug-in sensors, it is very easy to change sensors without tools. There is also no need to readjust the transmitter as the 6600 series sensors used in the 6651 have a fully digital interface to the transmitter, which is calibrated and adjusted on delivery.

The testo 6631 humidity transmitter has been specially developed for monitoring critical environments in greenhouses, and for research purposes. Accurate and reliable moisture measurements are indispensable in these programs, to avoid costs caused by failed experiments. Process safety and system availability are among the most important factors in experimental facilities.

The main benefits

• Testo’s highly accurate and long-term stable moisture sensor
• Robust enclosure
• -10…60°C
• 0…100%RH
• IP65
• Configuration, adjustment and analysis via the PC program P2A (accessory).
• Supply 20…30 V
• 4 … 20 mA (2 or 4-wire)
• Display (accessory)
• Long-term stability and reliability thanks to the accuracy of the Testo humidity sensor
• The integrated fan allows the directional flow impact on the sensor and helps to determine the average value in the greenhouse compartments.
• Thanks to its practical design, it protects its electronics and sensors from variations in humidity (e.g. sprinklers, irrigation, etc.).

This series of transmitters has interchangeable sensors, which are adapted to the application. Through the adjustment and setting software P2A you have total control over the instrument, you can scale/calibrate/adjust the output signal on all outputs including the analog output. In addition, the transmitter can be fed via USB. Adjustment or analysis can therefore be carried out without the need to run any other cables e.g. on the table or in the service workshop or areas without the possibility of power supply.

Using the optional display and the four buttons on the front, you can easily adjust, commission and analyze the instrument on site without a PC if you do not have access to one. Thanks to the new digital plug-in sensors, it is very easy to change sensors without tools. There is also no need to readjust the transmitter as the sensor is calibrated and adjusted before delivery. The Testo 6681 has an integrated Mollier chart which allows for a wide variety of selectable units.
