6631 humidity/temperature transmitter for greenhouses by Testo

The testo 6631 transmitter was developed specially for monitoring critical ambient conditions in greenhouses, e.g. for bio research purposes. Precise and reliable humidity measurement is indispensible in these applications, in order to avoid costs caused by failed experiments.

Process security and system availability, among the most important factors in experimental plants, are supported by a number of properties of the testo 6631 bio research transmitter.

  • P2A software for parameterization, adjustment and analysis saves time and costs in commissioning and maintenance
  • Integrated ventilator allows targeted flow impact onto the sensor, enabling the recording of an averaged climate inside the greenhouse cell
  • Quick and easy ventilator replacement with ventilator drawer assembly and plug-in connection
  • Easy exchange of sensor filter
  • Protection of the electronics and sensor from humidity influences (e. g. sprinkler)

Delivery Scope

  • testo 6631 humidity/temperature transmitter (measuring indicator) for greenhouses and laboratories with selectable signal outputs including instruction manual
  • Optionally with display
