Brief introduction: CA - PB0402 photosynthetic apparatus independent research and development of Beijing merchant, is a domestic leading level of the photosynthetic apparatus, the instrument after many years of successful efforts to research and development team for the outstanding contribution to the national agricultural project 863, have been highly praised the experts at home and abroad, and exported to European countries such as the United States. The degree of automation and portability of this instrument has surpassed the domestic equivalent of the instrument.PB0402 photosynthetic meter is small in size, light in weight, strong in user identification ability, high in automation, and many measurement items, etc. Function: ECA - PB0402 photosynthetic apparatus through the main measurements: leaf room temperature, leaf room humidity, temperature, co2 concentration, photosynthetic active radiation (photon flux density), voltage, can calculate the plant photosynthetic rate, transpiration rate, respiratory rate, stomatal conductance, stomatal resistance, intercellular co2 concentration, water use efficiency, light energy use efficiency, suitable for in ecology, agriculture, forestry, etc. Used in the research work. 1. It is used for the determination of various physiological indicators and ecological factors of plants, mainly photosynthesis, and for the determination of respiration of seeds, animals, insects and soil; 2. Measurement function: it has single-leaf open circuit, single-leaf closed circuit, group open circuit and group closed circuit measurement mode; Room 3, The main measurement index, leaf temperature, leaf chamber humidity, temperature, co2 concentration, photosynthetic active radiation (photon flux density), voltage, photosynthetic rate, transpiration rate, respiratory rate, stomatal conductance, stomatal resistance, intercellular co2 concentration, water use efficiency, light energy utilization efficiency of 14 indicators. 4, Environmental monitoring function, can monitor air temperature, air humidity, concentration of carbon dioxide in the air content and photosynthetic active radiation, the instrument can also act as environmental monitoring instrument is used, when set after the success to some point instrument automatic monitoring instrument is centered around 100 meters of atmospheric environment. 5. Measurement of multiple blades: the instrument can be equipped with multi-function composite leaf chamber and built-in light source, carbon dioxide gas mixer, group assimilation box and soil breathing apparatus. 6. Output of results: after the measurement, the user needs to modify the blade area to ensure the accuracy of measurement. Set up after the completion of the press save saved to the SD, when need to read the data users only need to pull out the SD card, and then can see directly with card reader computer measurement data, save the format for TXT document. 7. Storage function:The device USES a large-capacity SD card, and the standard configuration 4G can store 1 million sets of data, which can be expanded to 64 million sets. 8. Display function:7 inch touch screen, operation menu full screen display 9. Power supply function: Beijing yikangnong special DC7.4V7.6AH can store electric lithium battery, which can be used continuously for up to 9 hours after testing Features: 1. Integrated leaf chamber handle, carbon dioxide and moisture analysis system and leaf chamber integrated design. Infrared CO _ 2 / H _ 2O analyzer is placed in the leaf chamber, which eliminates the measurement delay and error caused by the use of long tubes to introduce the gas into the leaf chamber, and is more sensitive. High accuracy and fast response;More sensitive reflection, high measurement accuracy and fast response; 2. Innovative comprehensive gas analysis room, which can measure carbon dioxide and water synchronously in the same room, overcomes the unsynchronized phenomenon of common photosynthetic meter co2 and water measurement data in the market; 3. Touch the large screen design and display all operation menus in one piece to facilitate user operation; 4. Based on android system development, compared with single-chip microcomputer products, the operation is more intelligent and simple, opening a new era of intelligent photosynthetic meter. 5. Eca-pb0402 photosynthetic meter can expand chlorophyll fluorescence measurement system; 6. When entering the measuring interface, the change curve of carbon dioxide and humidity can be displayed; 7. Eca-pb0402 photosynthetic meter is a national patented product and has published many professional papers at home and abroad. Main technical parameters: CO2 sensor: non-dispersive infrared CO2 analysis, measuring range: 0-1500ppm, resolution: 0.1 PPM, accuracy of 350PPm. Leaf chamber temperature sensor: imported high precision temperature sensor, measurement range: 0-50 ℃, resolution: 0.1 ℃, the error of plus or minus 0.1 ℃ Leaf temperature sensors: imports of platinum resistance, measuring range: 0-50 ℃, resolution: 0.1 ℃, the error of plus or minus 0.1 ℃ Leaf chamber humidity sensor: imported high precision humidity sensor, measuring range: 0~75 mmol/mol, accuracy: + 2.0mmol /mol Photosynthetic effective radiation sensor: a silicon photocell with a modified filter Range of measurement: 0-2742 molm-2•-1 Accuracy: less than or equal to 5 molm-2•-1 Flow meter: electronic flow meter Measurement range: 0-1.5l /min Resolution: 0.1L/min Error: plus or minus 3%.
