GASTEC Carbon dioxide concentration measuring device

It features an automatic calibration function (manual calibration with outside air is also possible). If the concentration is below 999 ppm, the indicator lights green; if it is above 1000 ppm, the indicator lights red; if it is above 1500 ppm, the indicator flashes red. You can check the CO2 concentration remotely using the app (Android, iOS, Windows). [Reference values] Building environmental hygiene management standards: 1000 ppm or less, school environmental hygiene standards: 1500 ppm or less. It can be installed as a freestanding or wall-mounted unit. Simply turn it on to check the CO2 concentration. Multiple units can be displayed simultaneously. Measuring carbon dioxide concentration (approximately 1000 ppm) is an effective way to measure air ventilation for infection prevention and confirm ventilation effectiveness. Use it as a sign to regularly ventilate offices or to appeal to customers in commercial facilities. (Note: Infection prevention measures require not only ventilation but also measures to avoid crowded spaces and close contact.) The indicator light will alert you when the CO2 concentration is high.
Use it as a guide for ventilation to prevent infection and improve work efficiency. The automatic calibration function allows for stable, accurate measurements over the long term (manual calibration is also possible). The Ministry of Health, Labour and Welfare recommends checking ventilation efficiency through CO2 measurement as an effective ventilation method for improving "enclosed spaces with poor ventilation" in winter. The Windows-compatible app (OS Windows 10 or later) allows you to save measurement data (CSV format) (heat index WBGT can also be recorded). Each compatible app displays the WBGT value (heat index) as a measure against heatstroke. It complies with the "Guidelines for Selecting Carbon Dioxide Concentration Meters" announced by the Ministry of Economy, Trade and Industry on November 1, 2021.

*Only carbon dioxide concentration is displayed on the product itself. *Temperature and humidity are only displayed on the app. *Please note. *In addition, the temperature and humidity displays are provided as a supplementary guide to the air environment, so they may not provide the same level of accuracy as dedicated thermometers and hygrometers. *Please note.
