Fruit and vegetable respiration tester IN-GX20

Fruit and vegetable respiration tester

1、 Instrument usage

The harvested fruit and vegetable products are still an independent living organism, and in order to maintain life, respiration is necessary. Respiratory function is the most important physiological metabolic pathway for horticultural products such as fruits and vegetables after harvesting. Respiratory intensity is an indicator of the strength of respiratory function and an important indicator that must be mastered in studying physiological changes and storage, transportation, and preservation of fruits and vegetables after harvesting.

The fruit and vegetable respiration meter uses a dual wavelength infrared carbon dioxide analyzer and a 7-inch Android display, specifically designed for measuring and analyzing the respiratory intensity of fruits and vegetables under storage conditions such as room temperature, refrigerated storage, controlled atmosphere storage, and supermarket refrigerators.

The characteristic of this instrument is that it can select different volumes of breathing chambers according to the size of fruits and vegetables, which accelerates the balance and measurement time; It can directly operate and display the CO2 concentration, O2 concentration, temperature, humidity, and change curve of the breathing room.

2、 Instrument features:

1. Android operating system, more convenient human-computer interaction operation

2. 7-inch high-definition touch screen, easy to operate and clear interface;

3. The gas flow rate can be directly set by the instrument to conduct experiments on the respiratory intensity of fruits and vegetables under different flow rates;

4. Specialized dynamic analysis software that can display the experimental process in real-time on Android screens, eliminating the need to copy data to the computer and organize analysis;

5. You can input elements such as the type, name, weight, place of origin, and picking date of the experimental fruit or vegetable;

6. Support WiFi and 4G networking; Data can be wirelessly uploaded to the cloud platform;

7. Storage space of 16GB, capable of storing over 100000 pieces of data;

8. Data can be directly exported to a USB drive through the USB interface;

9. After the detection is completed, the detection data results can be directly printed and uploaded;

10. Support GPS positioning;
