HMH is a series of electromechanical humidistats for control of humidifying and/or dehumidifying in HVAC systems. The HMH humidistat utilises human hair as its sensor medium. The hair stretches as the humidity increases and shrinks as the humidity decreases. These changes are then transmitted to a micro switch (or, optionally, to two switches).
