F-950 Handheld Ethylene Analyzer

The F-950 Three Gas Analyser measures levels of Ethylene, CO2 and O2 to maintain optimal produce quality at every phase of the supply chain.
The F-950’s versatile design allows it to be be scaled to many environments, from cold storage to transportation container.

Simple to operate and weighing less than a kilogram, the F-950 uses an electrochemical cell to measure ethylene between 0-200 ppm.
The F-950 is ideal for measuring ethylene production across a wide range of fruit types.

Ethylene affects ripening, aging, and spoilage in produce. The F-950 measures levels of ethylene, CO2 and O2 in the atmosphere, and can be scaled to many environments, from cold storage to warehouse to transportation container. Simple to operate and weighing less than a kilogram, the F-950 uses an electrochemical cell to measure ethylene in air. It records date, time, relative humidity, and GPS location. The F-950 is ideal for measuring ethylene production across a wide range of fruit types and is especially suitable for managing ethylene emissions from perishable cut produce products.

Modified Atmosphere Packaging Applications

Most MAP gas analysers are equipped to only measure CO2 and/or O2 concentrations.
Quality assurance for perishable cut produce demands a more comprehensive analysis.
The F-950 makes it possible to respond to the change in ripening gases to ensure longer shelf-life and higher quality commodities.
