The 1% CO2, temperature and relative humidify portable environmental data logger is designed to measure up to 1% carbon dioxide (10,000ppm), temperature, and relative humidity in remote locations. It “wakes up”, takes readings, stores them in memory, and goes back to sleep.

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 such as OSHA.

This combination of functions provides for a portable monitor alarm system meeting the requirement of Indoor Air Quality surveys as well as OSHA safety standards.
