CO2 Sense Data LoggerThe CO2-Sense range of meters are designed to measure carbon dioxide (CO2), temperature and relative humidity with a self-contained data logger. There are also options for audible alarms and LCD display screen.

The CO2-Sense meters are portable or wall mounted environmental data logger designed to measure up to 1% (10,000ppm) or 30% (300,000ppm) carbon dioxide, temperature, and relative humidity in remote locations. It “wakes up”, takes readings, stores them in memory, and goes back to sleep.

The CO2-Sense operates off AA-batteries or can be connected to mains power supply for long-term monitoring.  The battery operated logger can save up to 15,000 data points at a time, including date, time, CO2, temperature and %RH.

In addition, the data logger has a built-in audible (80db) alarm and a LCD back-lit display that provides visual indication of the current CO2 conditions; Green, Yellow, and Red. The alarm is set by default for LEED levels, but can be user programmed to other standards.

This combination of functions provides for a portable monitor alarm system meeting the requirement of Indoor Air Quality surveys.
