Optical hygrometer
WebOptical hygrometers can be calibrated with gases with a given humidity. For this, a calibration tunnel is installed in the optical path and the calibration gas flows through at a controlled and not too large flow rate. The zero-point must first be calibrated normally with dry nitrogen gas. Next, for the span calibration, a certain water-vapor ...
