MacView Ethylene Postharvest Fixed Analyser
The MACView® Ethylene Postharvest Analyser is the most reliable analyser if you want to measure ethylene (Iso name ethene). It is a ready to work device at which you can choose from 3 different measurement ranges. The lowest measurement range from 0-2000 ppb with a resolution of 1 ppb is the best machine if you have a mission critical application. For example the monitoring of soft fruit, like kiwi’s with a harmful detection limit of 40 ppb is a perfect application for the MACView® Ethylene Postharvest Analyser .
To control your process the MACView® Ethylene Postharvest Analyser has more then 60 internal checks to assure your machine doesn’t make measurement faults. If a situation is not reliable, the machine will warn you automatically. The MACView® Ethylene Postharvest Analyser has all things on board that are necessary for a high quality measurement. For example there is place for an internal calibration bottle. The span calibration or the zero calibration can be performed by the machine itself, determined by the intervals that the user prefer
The MACView® Ethylene Postharvest Analyser is especially build to connect it to a multiplexer sampling system. The machine is able to sample the rooms in order that is asked by a central computer of the customer. The signal transfer of the measured values can be simple 4-20 mA, 0-10V or up to RS232 or RS485 communication if desired.
For international customers the machine is very maintenance friendly. All parts are available and easy accessible. The MACView® Ethylene Postharvest Analyser will give an announcement on some parts if this parts have to be replaced.
The machine is tested by the Wageningen University & Research. The machine is exposed to extreme O2, CO2, ethanol, relative humidity and temperature variations. The results of this test are excellent and can be downloaded.
