Notify the timing of ventilation with sound and light

CO2 carbon dioxide measuring instrument (with temperature/humidity meter)

It is a CO2 carbon dioxide measuring instrument that measures and displays CO2 (carbon dioxide), temperature, and humidity.
You can watch the air environment such as the living room/children’s room in the home, office/meeting room of the company, and public facilities such as the library, hotel room, farm greenhouse, and car.
When the concentration of CO2 (carbon dioxide) becomes high, you will be notified by sound and light, so you can know the timing of ventilation immediately.

Measures CO2 (carbon dioxide), temperature and humidity

It is a measuring instrument that detects CO2 (carbon dioxide) and displays a numerical value on the display. Since temperature and humidity can also be measured, it is possible to grasp the indoor environment.

Measures CO2 (carbon dioxide), temperature and humidity

When the CO2 concentration status becomes high, you will be notified by sound and light.

When the CO2 concentration becomes higher than a certain level, you will be notified by the LED of the main unit and an alert. Since you will be notified by sound and light, you can immediately grasp the change in CO2 concentration.

Light and sound change depending on the value of carbon dioxide concentration

The standard for indoor carbon dioxide concentration is 1000ppm or less, which is recommended by the Ministry of Health, Labor and Welfare.
This product changes the LED color and alarm sound in the range of 400 to 1000ppm, 1000ppm to 2000ppm, and 2000ppm.

Recommended for schools, stores and medical facilities

It notifies you of the timing of ventilation with sound and light, so it is recommended for places that require regular ventilation, such as schools and medical facilities.

Show battery level icon

The battery level icon is displayed so that you can check the charging timing. Charging is easy with the included Type-C-USB A cable.
AC adapter is sold separately.

Can be temporarily fixed to the wall

This product is a desktop installation type, but it can also be temporarily fixed to the wall using screws or the like.

Features of CHE-C1

It is a CO2 carbon dioxide measuring instrument that measures and displays CO2 (carbon dioxide), temperature, and humidity.

We monitor the air environment such as living rooms/children’s rooms in the home, offices/conference rooms in the office, and public facilities such as libraries, hotel rooms, farm greenhouses, and cars.

When the concentration of CO2 (carbon dioxide) becomes high, it will notify you by sound and light.

It can also run on the built-in battery.

Since the battery level icon is displayed, you can see the guideline for charging.

Charging can be done easily with a USB charging cable.
The AC adapter is not included, so please prepare it separately.

The NDIR sensor method recommended by the Ministry of Health, Labor and Welfare is adopted
