Description
The HALE AIR SENSE measures air quality precisely according to five different aspects; temperature, relative humidity, CO2 (carbon dioxide), TVOC (hydrocarbons) and PM (particulates). All with high-quality components. Particulates are measured in units of 0.3 PM, 0.5 PM, 1.0 PM, 2.5 PM and 10 PM and threshold values indicate when the air is good or bad. Colour indicators on the CO2 sensor in green, orange and red indicate when ventilation is required.
TEMPERATURE
The optimal temperature indoors is between 18 and 24 degrees. Relative air humidity influences the perceived temperature in a room. Keeping relative air humidity in winter between 40% – 60% can save on energy bills as the thermostat can be set one degree lower.
CO2
Carbon dioxide (CO2) is a gas that naturally occurs in the atmosphere. CO2 levels are expressed in PPM (parts per million). Too much CO2 suppresses oxygen intake in the body. As a result, the body expends less energy, leading to fatigue, headaches and loss of concentration. The ideal concentration of CO2 in the air is 400 to 800 ppm and the threshold value is set at 1200 ppm in the “Regular” setting mode.
RELATIVE AIR HUMIDITY
This is the maximum percentage of moisture in the air at a certain temperature and air pressure. A percentage between 40% – 60% is ideal,and can also reduce viruses. Too muchhumidity can cause mould growth.Too little humidity (dry air) is detrimental tomucous membranes, the eyes, nose, throatand skin. It can also lead to reducedresistance to infections. Dry air also influences materials like wooden floors, instruments and artworks.Plants grow and look better with healthy air humidity levels.
TVOC
Collective term for a group of hydrocarbons that evaporate easily (Total Volatile Organic Compounds). These chemicals occur in things like building materials, cleaning agents and paint. Short-term exposure causes irritation to the eyes and mucous membranes.
High concentrations can have health consequences for other organs. The optimum value would lie below 500 PPB (parts per billion). Levels above 1000 PPB should be avoided.
PARTICULATES | PM
A collective term for small airborne particles. These are invisible to the naked eye. Almost all human activity creates particulates. The smaller the particles, the greater the danger they pose to health. PM 1 (particulate matter) refers to ultrafine particles. Ultrafine particles land in the lungs and are especially dangerous for children and adults with lung conditions. The particulate level advised by the WHO is 45 μg/m3 for PM10 and 15 μg/m3 for PM2.5.
