Model: CHE-C2

Measures CO2 (carbon dioxide), temperature and humidity

A wall-mounted CO2 carbon dioxide monitor 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.

 

 

When the CO2 concentration status becomes high, the LED will notify you.

When the CO2 concentration becomes higher than a certain level, the LED on the main unit will notify you. Since the meter lights up based on the measured value of CO2 concentration, the change can be grasped immediately and the timing of ventilation can be known immediately.

 

 

When the CO2 concentration exceeds the set value, you will be notified by sound.

It is also possible to set an alarm to sound when the CO2 (carbon dioxide) concentration exceeds the set value. You can also set the alarm sound ON / OFF.

 

Recommended for offices, schools and medical facilities

Since the timing of ventilation can be known by sound and LED, it is recommended for places where regular ventilation is required. The large display makes it ideal for public and commercial facilities such as offices, conference rooms, schools, libraries and hospitals.

Power supply type by AC adapter

Power is supplied from the AC adapter, so there is no need to worry about running out of charge.

Can be installed on the wall

Since there is a hole for hanging on the wall, it can be installed by hooking it on a hook attached to the wall. When fixing to concrete with an electric drill, attach the attached anchor and tapping screw.

Features of CHE-C2

A wall-mounted CO2 carbon dioxide monitor that measures and displays CO2 (carbon dioxide), temperature, and humidity.

You can watch the indoor air environment such as offices / meeting rooms of companies, public facilities such as schools, libraries and hospitals, and commercial facilities.

When the concentration of CO2 (carbon dioxide) becomes high, it will notify you with an alarm sound and LED.

You can set the alarm to sound when the CO2 carbon dioxide concentration exceeds the set value. You can also set the alarm sound ON / OFF.

AC power supply type.

Correction function (calibration function)	If the correction function is used continuously for 5 to 7 days with the power turned on, accurate automatic correction (calibration) will be executed. <What is automatic calibration (correction)>* Although it depends on the product, it is a function that considers the minimum measured value of carbon dioxide for 5 to 7 days as 400PPM and corrects it step by step. * The reason why 400PPM is the standard is that the World Meteorological Organization (WMO) has announced that the average weekly CO2 concentration in the world is 400PPM, so 400PPM is the standard value.
