2-Step Humidistat
The HMH tube humidistat has two micro switches. The step differential between them can be set by means of the adjustment screw.
High accuracy measurement
The humidistat uses human hair as the sensor medium. This stretches as the humidity increases and shrinks as the humidity decreases.
High Degree of Accuracy
The tried and tested construction of the HMH tube humidistat guarantees high levels of accuracy and reliability.
The HMH humidistat is a 1 or 2-step electro-mechanical humidistat for controlling humidifying and/or dehumidifying in HVAC systems. The tried and tested construction of the HMH guarantees a high degree of accuracy and reliability. The humidistat uses human hair as the sensor medium. The hair stretches as the humidity increases and shrinks as the humidity decreases. These changes are then transmitted to a micro switch. The humidistat features 2 microswitches and the step differential between the two can be set by means of the adjustment screw.
As the contacts are of the changeover type the humidistat can control both humidification and dehumidification. It can also be used to alarm when the humidity exceeds or falls below a pre-set level. HMH can be mounted in a ventilation duct or on a wall. The humidistat is supplied with a flange which is suitable for both positions. HMH's form of protection is IP54.
