Fruit and vegetable respiration meter
I. Instrument Application
Harvested fruits and vegetables remain independent living organisms, and respiration is essential for their survival. Respiration is the primary physiological metabolic process for horticultural products such as fruits and vegetables after harvesting. Respiration intensity is an indicator of the strength of respiration and is a crucial indicator for studying the physiological changes of fruits and vegetables after harvesting and for storage, transportation, and preservation.
This fruit and vegetable respiration analyzer uses a dual-wavelength infrared carbon dioxide analyzer and a 7-inch Android display. It is specifically designed for measuring and analyzing the respiration intensity of fruits and vegetables under storage conditions such as ambient temperature, cold storage, controlled atmosphere storage, and supermarket freezers.
The instrument's features include the ability to select respiration chambers of different volumes according to the size of the fruits and vegetables, accelerating equilibration and measurement time; and direct display of CO2 concentration, O2 concentration, temperature, and humidity within the respiration chamber, along with their variation curves.
II. Instrument Features:
1. Android operating system for more convenient human-computer interaction.
2. 7-inch high-definition touchscreen, simple operation and clear interface.
3. Gas flow rate can be directly set through the instrument, allowing for experiments on the respiration intensity of fruits and vegetables at different flow rates.
4. Dedicated dynamic analysis software allows real-time display of the experimental process on the Android screen, eliminating the need to copy data to a computer for processing and analysis.
5. Input of elements such as the type, name, weight, origin, and harvest date of the tested fruits or vegetables.
6. 16GB storage space, capable of storing over 100,000 data entries.
7. Data can be directly exported to a USB flash drive via the USB interface.
