707 CX

Compact Handheld Emissions Analyzer 


Fast, Accurate and Low Maintenance

The COSA XENTAUR™ 707 CX™ Compact Handheld Emissions Analyzer is a portable, battery-operated device designed to measure and analyze emissions from a wide range of combustion sources. It is a highly versatile instrument that can be used to monitor emissions from stationary sources such as boilers, furnaces, and incinerators, as well as from mobile sources such as vehicles and marine engines.

The 707 CX Compact Handheld Emissions Analyzer is capable of measuring a variety of gases and pollutants, including oxygen (O2), carbon monoxide (CO), nitrogen oxides (NOx), sulfur dioxide (SO2), and hydrogen sulfide (H2S), as well as calculating combustion efficiency and carbon dioxide (CO2) levels.


Some of the key features and benefits of the 707 CX Compact Handheld Emissions Analyzer include:

  • Portability: Is small, lightweight, and battery-operated, making it easy to transport and use in the field.
  • Accuracy: The analyzer uses advanced electrochemical sensors and infrared sensors to measure gas concentrations with high accuracy and precision.
  • Fast Response Time: Has a fast response time, allowing users to quickly detect and respond to changes in gas concentrations.
  • Data Logging: Can store up to 1000 measurements in its internal memory, allowing users to record data over time and analyze trends.
  • User-Friendly Interface: Has a simple, intuitive user interface that makes it easy to operate, even for non-experts.
  • Wireless Connectivity: Can connect wirelessly to a smartphone or tablet via Bluetooth, allowing users to view real-time data and control the analyzer remotely.
  • Compliance: Compliant with all relevant emissions regulations, including US EPA, EU, and Asian standards.

The portability, accuracy, fast response time, data logging capabilities, user-friendly interface, wireless connectivity, and compliance with emissions regulations makes it an essential instrument for emissions testing and control in various industries.
