F-920

Check It! Gas Analyzer


The F-920 Check It! Gas Analyzer is a device that rapidly measures CO2 and O2 from 0-100%. Designed for QA personnel to take precise and speedy measurements of CO2 and O2, the Check It! displays results in less than
6 seconds and has a sampling volume
of 6.5 mL. 

The Check It! CO2 / O2 gas analyzer features an intuitive user interface, and lightweight design, which makes it easy for quality control managers to take measurements straight out of the box, and virtually anywhere in the supply chain. A built-in data logger stores thousands of data points and conveniently communicates data through USB or Bluetooth onto a PC or tablet for later analysis.
