techno line Technoline WL1028 Co2 Meter Indoor Air Quality Monitoring Recommendation Based on CO2 Concentration in the Air, Adjustable Alarms, CO2 History, for Schools, Hotels, Offices

Breathe healthy and happy. Many people attach great importance to healthy diet and sufficient drinking, but often forget the most important basic function of the body: breathing. An adult person drinks an average of 3 litres of liquid per day and can use up to 3 days without water, but in comparison an average of 15 kg of air is inhaled and without oxygen, the body would last only 3 minutes. More and more diseases with poor air quality and high concentrations of volatile organic compounds (VOCs) are also circulated. Through almost all furnishings, electrical appliances, chemical detergents, food preparation and people themselves, an unhealthy level of VOCs can be quickly achieved in enclosed spaces. With the WL 1028 air quality monitor, you can quickly and easily ensure more health and well-being through better room air. What can you find from the display?
