EXTECH SD800 Temperature/Humidity/CO2 Data Logger

EXTECH SD800 Temperature/Humidity/CO2 Data Logger

This Extech SD800 datalogger is especially suitable for monitoring air quality in schools, office buildings, greenhouses, hospitals and anywhere that high levels of carbon dioxide are generated. The Extech SD800 CO2/humidity/temperature datalogger features a maintenance-free dual wavelength NDIR (non-dispersive infrared) CO2 sensor that checks for carbon dioxide concentrations. The SD800’s triple LCD simultaneously displays CO2, temperature and relative humidity.

As part of its features, the Extech SD800 measures carbon dioxide from 0 to 4,000ppm. Extech SD800 dataloggers also offer ±40 ppm accuracy for values < 1,000 ppm and ±5% rdg for values > 1,000 ppm. The SD800 measures temperature from 32°F to 122°F (with ±1.8°F accuracy) and humidity from 10 to 90% (with ±4% RH accuracy) as well. The datalogging function of the SD800 provides a date/time stamps and stores readings on an SD card in Excel format for easy transfer to a PC.
