Brannan Carbon Dioxide Detector – CO₂, Temperature & Humidity Air Quality Monitor (Code 80484)

The Brannan Carbon Dioxide Detector is a multi-parameter air quality monitoring device designed to measure carbon dioxide (CO₂), air temperature, and relative humidity. It is intended for use in enclosed environments such as classrooms, offices, and public spaces where ventilation is an important factor in maintaining healthy air quality.

By measuring CO₂ levels, the device helps assess ventilation efficiency, as elevated carbon dioxide concentrations can indicate poor air circulation. This is particularly relevant in understanding indoor air quality and reducing the risk of airborne transmission of infectious diseases such as COVID-19.

The detector uses a high-precision NDIR (non-dispersive infrared) sensor for accurate and sensitive CO₂ measurement. It features a rechargeable lithium battery, allowing portable use across different locations, and includes a USB charging cable for convenient recharging via a PC or mains adapter.

A built-in power-saving function automatically switches the device off after 30 minutes of inactivity. The unit also includes a calibration certificate for verified accuracy.
