Extech SD800 CO2 Humidity and Temperature Datalogger
What is the Extech SD800 CO₂ Humidity and Temperature Data Logger?
The Extech SD800 CO₂ Humidity and Temperature Data Logger is a professional indoor air quality monitoring tool designed for HVAC engineers and facilities technicians who need reliable long-term data on ventilation effectiveness. It continuously records carbon dioxide (CO₂), temperature and relative humidity, storing readings directly to an SD card for easy analysis.
Using a maintenance-free dual wavelength NDIR CO₂ sensor, the SD800 delivers stable and accurate measurements in environments such as schools, offices, hospitals, plant rooms and commercial buildings where CO₂ levels can rise due to occupancy or poor airflow. Data is logged with a date and time stamp in Excel format, allowing quick transfer to a PC without specialist software.
How does the SD800 support indoor air quality monitoring?
With selectable logging intervals from 5 seconds to 10 minutes or automatic mode, the SD800 adapts to short investigations or extended monitoring periods. The triple LCD display shows CO₂, temperature and humidity simultaneously, making it easy to review conditions on site while still capturing detailed data for reporting.
