Humidifier

Belongs to:
Climatization
Description:

A humidifier is an electric device for enriching ambient air with humidity which is achieved by the evaporation of distilled water. The alternating electric and magnetic fields at the fundamental frequency of 50 Hz respectively 60 Hz are caused by the operation of the heating process of the water.

Frequency ranges:
  • 50–60 Hz
Type of field:
electric and magnetic

Measurements (acc. to literature)

Measurand Value Feature Remarks
electric field strength 1.287 kV/m (maximum, calculated) - at the surface of the device at 50 Hz [1]
magnetic flux density 220–1,020 µT (mean, measured) - range that results from the measurement of three different devices [2]
magnetic flux density 399 µT (maximum, calculated) - at the surface of the device at 50 Hz [3]
