Hygrostat, 40 → 90%RH, 230 V ac/dc

FLZ series hygrostats switch on control cabinet heaters or filterfans when a preset relative humidity is exceeded. The relative humidity is kept above the dew point and the condensation of water on electrical components, and corrosion of unprotected sheet metal, is prevented. The electronic combination device unites in one housing the thermostat and hygrostat, which monitor relative humidity and temperature independently of each other.
