A fruit and vegetable respiration intensity meter is an instrument specially used to measure the respiration intensity of fruits and vegetables. Fruit and vegetable respiration intensity refers to the amount of carbon dioxide released by fruits and vegetables during growth, development and ripening, which is one of the important parameters reflecting the vitality status of fruits and vegetables. By measuring the respiration intensity of fruits and vegetables, we can understand the freshness, ripeness, storage conditions and other aspects of fruits and vegetables, which is of great significance for fruit and vegetable preservation and quality control.
The working principle of the fruit and vegetable respiratory intensity meter is based on gas analysis technology, which determines the respiration intensity of fruits and vegetables by measuring the amount of carbon dioxide released. Instruments are usually equipped with carbon dioxide sensors, which can monitor the concentration of carbon dioxide released by fruits and vegetables in real time and convert it into respiration intensity values. At the same time, the instrument is also equipped with temperature and humidity sensors, which can measure the environmental conditions of fruits and vegetables, providing a guarantee for the accuracy of measurement results.
The precautions for the use of fruit and vegetable respiratory intensity tester include the following aspects:
Instrument placement environment: The fruit and vegetable respiratory intensity tester should be placed in a dry, well-ventilated place without direct sunlight, avoiding humid and high temperature environments, so as not to affect the normal operation and measurement accuracy of the instrument.
Instrument Cleaning and Maintenance: Instrument surfaces should be kept clean to avoid the accumulation of dust and dirt. The inside of the instrument should also be cleaned and maintained regularly to ensure its normal operation and prolong its service life.
Preparation before operation: Before using the fruit and vegetable respiratory intensity tester, check whether the power cord is in good condition to ensure that the power supply is safe and reliable. At the same time, check whether the instrument probe is clean and dry, and preheat and calibrate according to the requirements of the instrument manual to ensure the accuracy of the measurement results.
Sample Handling: Fruit and vegetable samples used for measurement should be properly processed beforehand, such as peeling, slicing, or crushing, to expose enough pulp tissue for instrumental measurement. At the same time, the sample should avoid containing too much water or impurities, so as not to affect the accuracy of the measurement results.
Measurement operation: Before placing the sample into the instrument, the lid of the instrument probe should be closed to avoid affecting the measurement results. During the measurement process, the instrument should be kept stable and vibration or movement should be avoided so as not to affect the accuracy of the measurement results. At the same time, correct operation should be carried out according to the operating instructions of the instrument to avoid inaccurate measurement results or damage to the instrument caused by misoperation.
Post-measurement treatment: After the measurement is completed, the sample container and instrument probe should be cleaned in time to avoid contamination or damage to the instrument caused by residues. At the same time, the measurement results should be recorded and analyzed to understand the respiratory intensity and freshness of fruits and vegetables.
Instrument safety: In the process of using the fruit and vegetable respiratory intensity tester, attention should be paid to safety and avoid contact with dangerous parts such as heating elements and high-pressure parts of the instrument. At the same time, the power cord, plug and other parts of the instrument should be checked regularly to prevent the occurrence of electrical accidents such as leakage and short circuit.
Comply with relevant regulations: In the process of using the fruit and vegetable respiratory intensity tester, you should comply with relevant laws, regulations and standard requirements, such as product manuals, laboratory safety specifications, etc. At the same time, the quality and performance of the instrument should be regularly checked and calibrated to ensure that it meets the requirements of the relevant standards and regulations.
In summary, when using the fruit and vegetable respiratory intensity tester, attention should be paid to the placement environment, cleaning and maintenance, pre-operation preparation, sample handling, measurement operation, post-measurement processing, instrument safety and compliance with relevant regulations. Only the correct use and maintenance of the instrument can ensure its accuracy and reliability, and provide a reliable basis for fruit and vegetable preservation and quality control.
