The Stego ETF 012 series electronic hygrotherm senses the ambient temperature and relative humidity in an enclosure with electric/electronic components and turns on a heater (or alternatively a fan) at either set point, helping to prevent the formation of condensation in the enclosure. Due to the wide voltage range of the Stego ETF 012 series hygrotherm, the device can be utilised anywhere in the world. The optional external sensor can be positioned freely anywhere in the enclosure for precise measurements.
