Ripening Gas (Ethylene / C2H4) Transmitter

Model No: PDS-EC-TX-RG3

This is the only fixed measurement solution operators should consider for ethylene monitoring.

Fixed ethylene detection in cold rooms gives operators and managers more confidence and control over room conditions. This leads to savings by optimising ethylene gas use and other catalytic generators. By monitoring the conditions and produce outcomes, operators can learn the best conditions for their product and reduce wastage and improve quality by having confidence in the environment.

Traditionally operators have relied on portable sensors and observation of the produce to make estimations about ethylene levels in rooms. These practices are inferior to the reliable fixed measurement of ethylene with around the clock readings and confidence in results and rooms.

The Effects of ethylene during the ripening of climacteric fruits

Ethylene production is closely associated with fruit ripening in climacteric fruits and is the plant hormone that regulates and coordinates the ripening process; colour development, aroma production and texture. Typically, climacteric fruit will generate barely detectable amounts of ethylene until ripening when there is a burst of production.

Ethylene as a ripening trigger is used commercially with many fruits including bananas, avocados and early-season kiwifruit to ensure that fruit are ripe when required. If the fruit is to be stored for a long time, then ambient ethylene must be removed from the room (usually by scrubbing this gas from the cool room).

The following table shows some appropriate ethylene gas levels, ethylene exposure times and temperatures for ripening certain commodities. Relative humidity should always be high, generally in the range of 80-95% for all commodities.

Specifications

We offer a range of high-quality Australian-made sensors for use in conjunction with, or independent of, the FreshView® EC12 Environmental Controller. Sensors are available for the detection of ripening gas (ethylene), carbon dioxide, temperature, relative humidity, pulp temperature and oxygen. Each sensor provides an analogue output signal and is housed in an enclosure that provides suitable protection against water and dust ingress (IP651). Sensors can be interfaced with other monitoring and control systems, including those manufactured by third parties.
