Rechargeable Data Logger: 1% CO2, Temp & %RH

The K-33 ELG Portable Environmental logger measures carbon dioxide (CO2) 0-1% (0-10,000ppm), temperature, and relative humidity in remote locations. It “wakes up”, takes readings, store them in memory, and go back to sleep.

The logger is rechargeable with a built-in lithium ion battery, recharged via USB connection. The battery has an endurance of 8,000 measurements before recharging and will hold up to 5400 data points.

Note that the K-33 ELG sensor inside is not designed for real-time data acquisition. They are designed to remotely log CO2, RH and temperature into log files for downloading at a later time. Logging interval is programmable from 30 seconds to 10 days.

Free Easy-to-use Software

This device is compatible with CO2 Meter's fully-featured data acquisition system (DAS) software. This software has been built from the ground up to allow for easy configuration, data collection, and calibration of your data logger. Available completely free of charge on our website, this software allows you to download logs, analyze, and export your data in report form, and as a CSV file for importation into industry-standard data logging packages.
