The Alecto WS-05WH is a compact, analogue hygrometer that allows you to measure the relative humidity in your home easily and reliably. A healthy humidity level is essential for your wellbeing and for maintaining a pleasant indoor climate. Thanks to its battery-free operation, the WS-05WH is environmentally friendly, maintenance-free and always ready for use.
The hygrometer is ideal for almost any indoor space, such as the bedroom, living room, basement, bathroom, greenhouse, conservatory, terrarium, office and more. With its colour indicator for the comfort zone, you can instantly see whether the humidity level falls within the recommended range.
What is a hygrometer?
Just as a thermometer measures temperature, a hygrometer measures the relative humidity level in a room. This percentage indicates whether the air is too dry, too humid or within a healthy range. For a healthy indoor climate, the ideal value is typically between 40% and 60%.
With the Alecto WS-05WH you can measure humidity accurately and reliably, with a measuring range of 0–100% relative humidity. This allows you to check each room individually to determine whether there is excess moisture or, on the contrary, air that is too dry.
What does relative humidity mean?
Relative humidity expresses the ratio between the amount of water vapour present in the air and the maximum amount of water vapour the air can hold at a given temperature.
When the air is fully saturated, the relative humidity is 100%. If the moisture content rises beyond this point, condensation begins to form — for example, on windows or walls.
Moisture in the home: more common than you think
Large amounts of moisture are produced indoors every day. People, animals and plants constantly release water vapour through breathing and perspiration. In addition, everyday activities such as cooking, showering, washing and mopping contribute extra moisture.
An average household of 3 to 4 people can produce as much as 10 litres of water vapour per day. Moisture can also enter the home through basements, crawl spaces or from outside air. Excess humidity increases the risk of mould growth, dust mites and an unhealthy indoor environment.
Why is healthy humidity important?
A good humidity level is essential for:
- Reducing health complaints (respiratory issues, allergies, skin problems)
- Preventing mould and mites
- Protecting wooden floors, furniture and musical instruments
By measuring humidity regularly with the Alecto WS-05WH and ventilating or heating when necessary, you can maintain a humidity level between the ideal 40–60%.
