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 YT-GX20 new fruit and vegetable respiration meter uses a dual wavelength infrared carbon dioxide analyzer and a 3.5-inch TFT true color LCD 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; The instrument can be directly operated through a computer, while displaying the CO2 concentration, O2 concentration, temperature, humidity, and change curve of the breathing chamber.

Instrument features:

1. 3.5-inch TFT true color LCD display with a resolution of 320 × 480, easy to operate and clear interface

2. 32GB memory, large data storage capacity, or can be directly connected to a computer for testing, and data and curves can be saved on the computer.

3. Specialized dynamic analysis software that can display the experimental process in real time on a computer and input elements such as the type, name, weight, place of origin, and picking date of the tested fruits or vegetables.

4. The gas flow rate is set by instruments or computers. It is possible to conduct experiments on the respiratory intensity of fruits and vegetables under different flow rates.

5. Two operation modes: You can use the instrument alone to complete the experiment, or you can use the computer to operate the instrument to complete the experiment
