Function: The experimental teaching of plant physiological ecology in colleges and universities can determine and calculate many physiological and ecological indexes.This instrument adopts advanced automatic photosynthetic apparatus for determination of transpiration principle and structure device, but the measurement process and result calculation can be controlled and set by human.Through the operation of the equipment is to be able to make the student to the principle of determination of photosynthesis, transpiration, the structure of the measuring device, the measurement process, the results of calculation and measurement error analysis has a profound understanding of, to avoid the past teaching laboratory artificial design assembly measurement device caused by a series of inconvenience, so as to improve the teaching quality.At the same time, we can understand the working principle of advanced and fully automatic photosynthetic transpiration meter at home and abroad, which will lay a foundation for future research work. Main technical parameters: 2-1 Working conditions: temperature 0-50 ℃, relative humidity: 0-100% (no water vapor condensation); 2-2 Power supply: DC6V can store battery, or external 220VAC power adapter 2-3 CO2 analysis: non-dispersive infrared CO2 analysis, measuring range: 0-1000ppm, resolution: 1ppm, accuracy: 2ppm; 2-4 Temperature: thermistor, measuring range: 0-50 ℃, resolution: 0.1 ℃, the error of plus or minus 0.2 ℃; 2-5 Humidity: humidity-sensitive capacitance, measurement range 0-100%, resolution: 0.1%, error of plus or minus 2% or less (0-80%), plus or minus 4% or less (80-100%); 2-6 PAR: silicon photocell with modified filter, measuring range: 0-2742 mol-2 •s-1, accuracy <5 molm-2•s-1 2-7 flowmeter: measuring range: 0-1.5L/min, resolution: 0.1 L/min, error;Plus or minus 2%;
