CO2, Temperature & Humidity Detector

CO2 Detector Portable– A portable or wall mounted unit with alarms and data logging

The 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.

Free Easy-to-use GasLab® Software

This device uses GasLab® software for setup, calibration, data logging, and real-time data analysis. GasLab® makes it easy to export data into a .CSV file that can be imported into any industry-standard software or spreadsheet. GasLab® runs on Windows XP or higher, and free to use with our products.


CO2 Data Loggeroptions

Hydrophobic Vent Filter Kit – For high-humidity environments, these hydrophobic filters cover the inside vents to allow air flow but keeps out humidity that affects the sensor. Easy to install, each kit contains a set of filters for 1 unit.
