Product Description
Respiratory metabolism is the basic process that maintains energy metabolism in all animals and plants, and it is a fundamental biochemical process carried out by cells to sustain life activities. In green plants, respiration mainly occurs in chloroplasts. Through the combination of photosynthesis and respiration, plants can convert absorbed light energy into chemical energy and release energy through respiration to support their growth and development. The respiration of fruits and vegetables is a process in which they continuously absorb oxygen, release CO2, and consume nutrients during their life activities. It is an important index that must be mastered in studying the physiological changes, storage, transportation, and preservation of fruits and vegetables after picking. In animals, respiration involves inhaling oxygen to digest and decompose ingested organic compounds and exhaling CO2. The ratio of the amount of CO2 consumed to the amount of O2 consumed by an animal within a certain period is called the respiratory quotient (RQ). By measuring the amount of CO2 exhaled and the amount of oxygen consumed by an animal, we can understand the animal's respiratory metabolism. Product Introduction and Application
The respiration intensity measurement system consists of a CO2 sensor, an oxygen sensor, a multi - channel gas path converter, a micro - flow meter, a data collector, a touch - screen display, and a respiration chamber. The instrument can customize the corresponding measurement system according to the research content. If it is specifically used for the determination and analysis of the respiration intensity of fruits and vegetables under storage conditions such as normal temperature, cold storage, controlled - atmosphere storage, and supermarket freezers, the instrument is set to measure the CO2, O2, H2O, and temperature of the fruits and vegetables in the respiration chamber. Different - volume respiration chambers can be selected according to the size of the fruits and vegetables to accelerate the equilibrium and measurement time. If it is used to study insect respiratory metabolism, such as in insect physiology, insect ecology, pest control, etc., a single - channel or multi - channel measurement system can be customized according to the experimental requirements, and simultaneously measure the CO2, O2, RQ, and H2O in the respiration chamber.Measurement Methods
Closed - type measurement method (for fruits and vegetables).
Open - type measurement method (for insects).
Multiple - channel measurement can be selected for insect metabolism.Instrument Parameters

The insect metabolism measurement adopts an open - type gas path, and a multi - channel measurement method can be selected. There are 0 - 8 channels available for selection, each channel is controlled independently, and long - term measurement can be carried out.
The special respiration chamber is made of high - borosilicate glass, with flame - polished surfaces, ultra - low - permeability gaskets, and ultra - low CO2 and water vapor absorption or permeability. There are 3 standard models (other specifications can be customized): Type I: Inner diameter 20mm, internal length 12.7cm; Type II: Inner diameter 28mm, internal length 12.6cm; Type III: Inner diameter 60mm, internal length 25cm.
