CO2 monitor AT-C01 PLUS Plus

Notification of “ventilation” timing with LED color and numerical value
Illuminated pyramid design makes it easy to see and understand

The CO2 Monitor measures the CO2 concentration in shared spaces where people gather, such as offices, schools, medical institutions, and restaurants, and provides easy-to-understand notifications of ventilation timing from anywhere by changing the LED color of its pyramid-shaped design.

As thorough ventilation is required to prevent infection in indoor spaces, devices that measure the CO2 concentration in a space are increasingly being used as a guide for ventilation. On the other hand, there were issues such as the displayed CO2 concentration values being unfamiliar and difficult to understand, and also difficult to see from certain angles.

This product is equipped with an NDIR*1 sensor that measures CO2 concentration. In addition to the numerical value, the LED color changes to three levels (green, yellow, and red) depending on the concentration, giving you an easy-to-understand guide to ventilation. We also took into consideration visibility by adopting a pyramid-shaped design that makes it easy to see from a variety of angles, even from a distance. In addition to CO2 concentration, it can display three numerical values: temperature and humidity, which are necessary as a guideline for infection control.

This product was jointly developed as part of the activities of the new business subcommittee within the “Collaboration Promotion Project” operated by both Plus and Pentel.

Main product features

Lighting pyramid-shaped design makes it easy to see and understand the ventilation guidelines

When the CO2 concentration increases and exceeds the set value, the LED color changes from green to yellow to red. The entire cover is illuminated, so it is easy to notice even from a distance, and you can tell at a glance when to ventilate. (Threshold value can be changed)

Displays three types of information: CO2 concentration, temperature, and humidity

The CO2 concentration, temperature, and humidity required for ventilation are constantly measured*2 and the values are displayed at the bottom of the main unit.
*2 It does not measure the entire space, but the area around the device.

CO2 concentration threshold and brightness can be adjusted

You can set the CO2 concentration threshold at which the LED color changes to match the ventilation standards*3 that differ depending on the facility. In addition, the brightness of the LED can be adjusted in 3 levels depending on the brightness of the space.
*3 The standard value is 1,000ppm or less under the Building Management Act, and 1,500ppm or less under the School Hygiene Standards.

Selectable lighting modes

We have designed lighting modes that can be selected to suit the usage environment and to allow use even after the infection has subsided, such as an eco mode that lights only the red LED, and an off mode that turns off the LED and displays only the numerical value.

Characteristic and easily noticeable pyramid-shaped design

The simple yet distinctive pyramid shape makes it easy to see even from a distance, and the compact tabletop design allows it to be installed in a variety of locations.
