Humidifier (option)
The immersed-electrode humidifier is fitted with a microprocessor-based controller that adapts, within the allowable operating limits,
to the physical and chemical properties of the water used.
Voltage is applied to the electrodes immersed in the water; an electrical current passes between them, heating the water to boiling
point.
The water acts as an electrical resistance, ensuring continuity between the electrodes and a minimum of dissolved salts.

If a water softener or water treatment system is used, the water hardness should not be less than 40% of the initial hardness and
should never be less than 15°F. (TH = 150 mg/l CaC03)
