The F-900 Portable Ethylene Analyzer delivers real-time, non-destructive monitoring of ethylene, CO₂, and O₂ in a compact and portable platform. With detection limits as low as 25 ppb, it enables precise quality control and research in both laboratory and industrial settings.

Key Features

• Real-time, continuous measurement of ethylene, CO₂, and O₂
• High sensitivity: ethylene detection down to 25 ppb
• Fast results – measurements in seconds
• Portable, lightweight design for field or lab use

Applications

• Controlled atmosphere and storage

Monitor ethylene levels in controlled environments to prevent exceedance of critical thresholds.

• Flux and headspace analysis

Collect accurate ethylene emission data from single fruits or small-volume samples, including low-emission crops.

• Research and development

Support high-level research with reliable measurements of ethylene alongside CO₂ and O₂.

• Quality assurance

Ensure optimal ripening management and minimize postharvest losses.
