FS-3080D Pro Photosynthesis Meter Introduction: FS-3080D Pro photosynthesis instrument is used to measure the photosynthetic rate, transpiration rate, stomatal conductance of plant leaves and other parameters related to plant photosynthesis. The instrument uses high-precision infrared CO2 analysis sensors, imported temperature and humidity measurement sensors, and cosine-corrected PAR sensors to determine the effects of light intensity, CO2 concentration, and temperature and humidity on plant photosynthetic systems. Features: Measurement method: open circuit measurement Measurement items: leaf temperature; leaf chamber temperature; leaf chamber humidity Analysis and calculation: leaf photosynthetic rate (Pn); leaf transpiration rate (Tr); intercellular CO2 concentration (Ci); stomatal conductance (Gs) ; Water Utilization Efficiency (WUE); Respiratory Rate Measurement (Rd) can be added Technical parameter: CO2 Analysis: A temperature-regulated dual-wavelength infrared carbon dioxide analyzer is added, measurement range: 0-3000ppm, resolution: 0.1ppm; accuracy 3ppm. Leaf chamber temperature: German Heraeus high-precision digital temperature sensor, measuring range: -20-80°C, resolution: 0.1°C, error ±0.2°C Leaf temperature: Platinum resistance, measuring range: -20-60℃, resolution: 0.1℃, error ±0.2℃ humidity: High precision digital humidity sensor imported from Switzerland: Measuring range 0-85%, resolution: 0.1%, error ≤ 1% Photosynthetically Active Radiation (PAR): Silicon Photovoltaic Cells with Correction Filters Measuring range: 0-3000µmol•m -2•s-1 , accuracy <1µmol•m -2•s-1. Response wavelength range: 400～700nm Flow measurement: Micro electronic flowmeter, the flow can be set arbitrarily within the range of 0.2-1L. Resolution: 0.0001L, Zero drift: ±0.005L, the flow rate of the air pump can be set as required, and the influence of different gas flow rates on photosynthesis can be measured, and the gas flow rate is stable.
