Announcement of special price for CO2 monitor "Marvel Series"
We are selling CO2 monitors that can be used as a guideline for ventilation at a special price. There are three types available, including models for large spaces and those with data loggers. During the season when air conditioning is used, some people may close windows and stop ventilating. However, neglecting ventilation can lead to an increased risk of infectious diseases, as well as decreased concentration and drowsiness, which can affect work efficiency. Generally, it is said that a comfortable air quality guideline is below 1000 ppm. Please consider this opportunity. *For pricing, please inquire.
