Handheld photosynthetic apparatus

CI-340 Ultra Light Handheld Photosynthesis Measurement System - the most lightweight, convenient, and efficient photosynthesis analyzer. Make our work easy, even easier! As you can see before your eyes, the CI-340 photosynthesis measurement system is the world's most lightweight, convenient, and efficient handheld photosynthesis measurement system, making it an ideal field or field research tool for ecological researchers. It has a sturdy structure and is easy to carry. The entire system, including data display, operation keyboard, data storage, CO2/H2O analyzer, flow control system, rechargeable battery, various measuring probes and sensors, is artistically integrated into a small handle, it's so incredible! The functions of CI-340 almost cover all measurements and calculations related to photosynthesis and transpiration determination. Such as photosynthetic efficiency, stomatal conductance, intercellular CO2 concentration, transpiration rate, etc. You can read data and also see various response curves. Due to the direct connection between the leaf chamber and the CO2/H2O analyzer, there is no time delay in the measurement of CO2/H2O. By utilizing the technology of CID company, CI-340 can accurately control the CO2/H2O concentration in the blade chamber. CI-340 also has powerful accessories that allow researchers to control the light, temperature, water, and CO2 in the leaf chamber. These accessories are all separate from the host and can only be connected to the host when needed, making it more convenient for use and operation in the field. CI-340 also has a powerful sustainable power source to ensure that researchers can work continuously for more than 12 hours in the field. Features: The entire system is integrated into a handheld device box. It is lightweight and portable, weighing only 1.5kg (including an 8-hour battery). It can measure photosynthesis or respiration, with two measurement methods: open circuit and closed circuit. It has a fast continuous measurement function that can measure a set of data in 1 second. It is convenient to switch between graphic display and data display. It can be used as an environmental gas monitoring recorder. There are 9 types of leaf chambers to choose from. It is equipped with soil respiration chambers and group measurement accessories. Light control, water control/carbon dioxide control, temperature control and fluorescence measurement accessories can be selected. Accessories can be manually controlled or controlled by the main program. Photosynthesis and chlorophyll fluorescence technical parameters can be measured simultaneously. Main components: Power supply: 7.2mAh, rechargeable lithium battery that can be used continuously for 8 hours, or with an AC adapter, 6-12V DC input.
