Photosynthesis analyzer

■Instrument Introduction:

SY-1020HPhotosynthesis analyzerIt is achieved by measuring plant leaves over a certain period of timeCO₂The amount of absorption (release) is measured simultaneously, and factors such as air temperature and humidity, leaf temperature, leaf chamber humidity changes, and light intensity are measured to directly calculate the plant's photosynthetic rate, transpiration rate, and intercellular interactionsCO₂Photosynthetic indicators such as concentration and stomatal conductance.Photosynthesis analyzerHas sensitivitygaoDue to its outstanding advantages such as rapid response, strong anti-interference ability, easy operation, and the ability to perform live and continuous measurements, it has been widely usedguangWidely applied in multiple fields such as plant physiology, ecological environment, and agricultural science.

■Key Features:

Small and lightweight in appearance, easy to carry around, capable of measuring anytime, anywhere, and operated by a single person.

Color dot matrix LCD display screen, Chinese menu displays multiple information, cursor guides operation.

● You can set the modification date, time, leaf area, volume, measurement interval time, flow rate, username, etc.

● Measurement process andzuiThe final result is displayed instantly and can be stored.

● Measurement data toTXTDocument format storage, standard configuration2G SDCard,zuilarge storage capacity32G.

The measurement results include: photosynthetic rate, respiration rate, transpiration rate, stomatal conductance, intercellular carbon dioxide concentration, and water use efficiency, and can display the current test results in real time.

● CanoptionalVarious types of leaf chambers (reactors) are suitable for measuring different objects such as plant leaves, seeds, insects, etc.

Adopting dual humidity sensing modules and placing them at the head of the measuring handle can quickly respond to changes in humidity inside the leaf chamber, avoiding air path delays. Make the testing and calculation of transpiration rate and stomatal conductance more accurate and rapid.

Adopting two measurement modes, open circuit measurement and closed circuit measurement, users can flexibly choose different measurement modes according to different usage environments.

Adopting a miniature electronic flowmeter, the flow rate of the air pump can be adjusted as needed200-999umol/sAdjust within the range to measure the impact of different gas flow rates on photosynthesis, ensuring stable gas flow rates. At the same time, it has an air path blockage alarm prompt function to avoid testing errors and pump damage caused by air path blockage.

● Increase atmospheric pressure index and have pressure compensation function.
