The lightweight design and simple operation of the F-900 enables trace measurements of ethylene concentration in any location.
From cold storage to ripening rooms, the F-900 provides accurate measurement across an unparalleled range of ethylene concentrations (0-200 ppmv), with superior low-range resolution (1 ppbv).
Includes two Ethylene sensors 0-10ppm and 0-200ppm, the instrument switches between the two sensors depending on the C2H4 values.
The F-900 utilizes electrochemical sensors and proprietary PolarCept TM filtering technology to remove other hydrocarbons from the airstream, allowing measurements of ethylene to be made in under five minutes.
Optional accessories extend the use of the instrument to measure small volume samples (Injection Port Kit), for isolated measurements from a single fruit (Research Kit), and for the measurement of other gases (CO2 and O2).
Product Features
- High ethylene sensitivity (Resolution of 1 ppbv)
- Broad operating range (0-45 o C; 0-90% RH)
- Internal data logging and storage (4GB SD card)
- PolarCeptTM filter to remove non-ethylene compounds
Continuous Monitoring
For understanding daily changes of ethylene in any environment
Real-time Flux from Fruits
For studying ripeness and fruit maturation processes
GC Emulation Mode
For small-volume snapshots of ethylene concentration (requires optional accessories)
Analog & Digital Output
For communication with external devices
Injection Port Kit
The Injection Port Kit, (an optional accessory) employs a unique Flow Inject Analysis method (patent pending) to determine ethylene concentrations ranging from 0.5-200 ppmv with sample volumes from 3-13mL. Similar to gas chromatography, a simple estimation, accurate up to ± 0.1 ppmv, is made by comparing the area counts of the unknown sample to a known concentration.
Optional Sensors
Not only can you accurately monitor trace ethylene concentrations with the F-900, we also offer additional sensors for other gases. See back page for specifications.
Terminal Block
The removable, 4-20mA, terminal block allows the instrument to control user-supplied devices that regulate ethylene concentrations in a room. The digital and analog outputs can be used to trigger alarms, turn on exhaust fans, enable a gas valve, relay data, or for external monitoring purposes.
