This is a brand new, unused item.
We aim to ship the next day, but we do not ship on Saturdays or Sundays.

Digital sensor for measuring CO2 concentration, temperature, and humidity.

[Visualize CO2 Concentration with Numbers] Displays indoor CO2 concentration (ppm). Can be used as a guide for ventilation timing in rooms prone to stuffiness, conference rooms, and home office environments. *Displayed values may vary depending on environmental conditions.
[Measurement Range 400-5000ppm / For Daily Use] A range that is easy to use in typical indoor environments. The numbers tend to rise when more people are present or windows are closed, serving as a reference for ventilation decisions.
[Simultaneous Temperature and Humidity Display / Manage Indoor Environment at Once] Not only CO2 but also temperature and humidity can be checked on the same screen. Also useful for understanding dryness and stuffiness (displayed values are for reference). Can be used as a supplement when using air conditioning or for dryness prevention in winter.
[Type-C Charging / Built-in Battery for Portability] USB Type-C charging, 5V input. 1200mAh battery makes it easy to place anywhere (also easy to operate with a mobile battery). Power cord management is simple.
[Tabletop/Wall-Mounted Compatible / Compact Design] Compact size that can be used simply by placing it on a desk. Can also be wall-mounted using the hook hole on the back (mounting hardware sold separately). Widely compatible with living rooms, bedrooms, children's rooms, offices, stores, etc.
