The F-900 Portable Ethylene Analyser provides measurements of ethylene in real time. Quality Assurance professionals use the F-900 to collect the data they need to manage ethylene gas accurately and efficiently—in controlled atmosphere facilities, cold storage, and shipping containers
Until recently, sensitive ethylene measurements were available only through complex and expensive gas sampling and gas chromatography analysis. The F-900 is an economical, yet precise, solution to ethylene measurement.
The F-900 Research Kit enables the stand-alone unit to take in-situ measurements of ethylene flux from fruits and leaves non-destructively. By using the Injection Port Kit, users can take small-volume, point-in-time measurements of ethylene. Additional sensors for measuring CO2 and O2 can be added to the F-900 for complete ripening gas analysis

The F-900 is a versatile ethylene analyser available with the ability to: measure ethylene flux directly from a single fruit non-destructively, continuously monitor storage rooms, act as an alarm, fan, or gas controller, integrate with larger control systems, measure small-volume samples with GC emulation mode, and act as a portable inspection tool. The F-900 is sensitive to low levels of ethylene, but can also be used to measure ripening applications in high-ethylene environments. The F-900 includes a patented PolarCept water filter that removes interfering gases and hydrocarbons which would otherwise lead to an artificially elevated readings on the electrochemical sensor.
