testo 6651 – the humidity transmitter for stationary measurement of room air conditions and stationary measurement of production climate

• • Accuracy up to ±1.7 % RH
  • Digital probe of the 6600 instruments: can be calibrated and exchanged and is equipped with its own order number
    • Wall, duct and cable probes, can be configured upon customer request and are heat resistant up to +120 °C
  • Highest availability by means of early warnings, e.g. in the event of sensor failure, condensation etc. (preventative maintenance)
  • Different assembly variants:
    • Wall-mounted version
    • Duct version
    • Probe version
  • Optimum calibration concept with …

    • 1-point adjustment can be performed on-site easily and quickly using t400 or t650
    • 2-point adjustment via P2A software or user menu
  • Parameterizing, adjusting and analyzing software (P2A) for setting up, adjusting and analyzing the transmitter:
    • Parameterization of unit and scaling
    • Adjustment (see above)
    • Reset to factory settings
    • Testing of analog outputs/relays
    • Requesting of max./min. values
    • Parameterization and adjustment history: All activities of the P2A software are registered with an operating time stamp in the internal log
    • Serial number and firmware version can be called up

• Time-saving commissioning and maintenance via service flap and P2A software
• Perfect integration into all factory automation:
