The new CO2 (Carbon Dioxide) analyzers are designed to monitor CO2 (and in some cases, O2) for multiple applications. Some of these applications include the Horticulture, Food Processing, Science Research, Medical, and Brewing industries. These units have been developed to incorporate the latest technology and specification requirements that provide the user with a fast, simple-to-use analyzer. Each analyzer has a carbon dioxide sensor with built-in gas moisture removal, as well as improved accuracy on CO2 readings and quick verification of CO2 levels. The analyzers also feature large data storage and user friendly software for carbon dioxide monitoring and analysis. This carbon dioxide analyzer is also a time saving instrument because of its dual temperature probes, allowing for more versatile and accurate measurements in hard-to-reach areas. The CO2 is measured with the carbon dioxide sensor by custom dual infrared wavelengths. These units offer the most desirable qualities in a carbon dioxide analyzer: reliability, constant measurement, safety, and simplicity.
