Part #: 0555 6681

Description

  • Highest accuracy up to ±1.0 % RH
  • First humidity transmitter with Profibus-DP interface
  • Digital probe of the 6610 instruments: can be calibrated and exchanged and is equipped with its own order number
  • Probes for specific applications:
    • testo 6614: Heated probe for long-term high-humidity processes
    • testo 6615: Trace humidity measurement with automatic adjustment
    • testo 6617: Integrated sensor self-diagnosis
    • Further wall, duct and cable versions can be configured upon customer request and are heat resistant up to +180 °C
  • Highest availability by means of early warnings in the event of sensor failure, condensation etc. (preventative maintenance)
  • Optimum calibration concept with
    • adjustment of entire signal chain, including analog adjustment, without dismantling the transmitter
    • 1-point adjustment can be performed on-site easily and quickly using t400 or t650
