S503

 Relative Humidity Generator for Calibrations
The S503 Humidity Generator enables users of humidity sensors, transmitters and portable devices to quickly and accurately generate a stable humidity in a test chamber to validate or calibrate sensors.








Product Features

  • Generates humidity levels between 10-90% RH
  • Highly portable
  • Fast stabilisation of chamber humidity
  • Independent reference hygrometer-optional
  • Multiple sensors can be calibrated at the same time
