Humidistats have a wide range of applications in any equipment that needs to detect relative humidity and changes in humidity with high accuracy.
They not only detect the relative humidity level but also provide an automatic switching function based on the level at which the humidistat is set.
Because of this switching capability, they are essential components in electrical equipment like air conditioning, humidifiers/dehumidifiers and where it is desirable to control humidity, such as in refrigerators and microwave ovens.
Humidistats are sometimes also referred to as hygrostats; however, this term is also used for devices fitted with a thermally sensitive heater that controls the humidity level, whereas a humidistat itself typically functions as a switch.
Maintaining a stable moisture balance in your home is crucial to preventing over-humidifying, which can result in mould spores. Likewise having an overly dry room that can be uncomfortable. The recommended home humidity level is within the range of 45 to 60 per cent depending on your personal preference.
Galltec+Mela humidistats are a cost-effective solution for humidity monitoring and control, with low maintenance demands, a high humidity range and good long-term stability.
Their simple design is incredibly robust, giving them a long service life at a relatively low cost both in terms of initial purchase and ongoing maintenance costs.
A watertight POLYGA® measuring element gives these humidistats the ability to function at very high levels of relative humidity with a simple microswitch that is triggered by the change in the length of the watertight measuring element when the humidity changes.
Envin Scientific supply a wide range of Galltec+Mela digital humidity sensors and you can download detailed datasheets for all of the different humidistats, hygro-thermostats and hygroswitches from our website.
