High-Accuracy CO2 Analyzer
- Extremely Accurate
- Measures over a very wide range of concentrations
- Unsurpassed Performance
Insensitive to all other atmospheric gases, the High-Accuracy CO2 Analyzer measures carbon dioxide in dry ambient air with unprecedented accuracy and precision (total measurement uncertainty of less than 1 part in 3000). The instrument can store data practically indefinitely on its internal hard disk drive and can send real-time data to a data logger through its analog, digital (RS232), and Ethernet outputs allowing unattended long-term standalone operation.
Based on high-resolution direct-absorption spectroscopy (see Theory of Operation), the instrument offers negligible zero and span drift and a significantly reduced need for regular calibration with expensive reference gases (compared with conventional instruments). The High-Accuracy CO2 Analyzer is designed for applications that require the performance of a reference laboratory without the need for regular calibration with expensive gas standards.
