Plant Photosynthesis Meter

Plant Photosynthesis Meter Introduction:

GH2 Plant Photosynthesis MeterX is an experimental instrument for monitoring photosynthesis in live plant leaves in artificial climate chambers, greenhouses, sheds, and fields. It measures 15 parameters, including air CO2 concentration, ambient temperature and humidity, leaf room temperature and humidity, leaf surface temperature, atmospheric pressure, photosynthetically active radiation (PAR), leaf photosynthetic rate (Pn), stomatal conductance (Gs), leaf transpiration rate (Tr), intercellular CO2 concentration (Ci), water use efficiency (WUE), respiration rate (Rd), and transpiration ratio (TR). It can be used for scientific research on plant growth physiology, photosynthetic physiology, and stress physiology. This plant photosynthesis meter is suitable for agricultural research, teaching, horticulture, grassland, forestry, and a wide range of other fields.

Plant Photosynthesis Meter Product Features:

•Intelligent: Utilizes the Android operating system and features a highly sensitive touchscreen. Efficient human-computer interaction and real-time display of measurement progress provide a superior user experience.

•High Stability: The dual-wavelength infrared CO2 analyzer, equipped with temperature control and atmospheric pressure measurement units, effectively improves CO2 stability and accuracy, effectively avoiding the drawback of large fluctuations in CO2 readings due to temperature changes.

•Multifunctional: Simultaneously measures photosynthetic rate, transpiration rate, intercellular CO2 concentration, stomatal conductance, and water use efficiency, as well as CO2 concentration, relative humidity, photosynthetically active radiation, air temperature, leaf temperature, and atmospheric pressure.

•Customization: Users can edit experimental notes based on their measurement needs and display Pn curves, Tr curves, light-photosynthesis curves, and humidity-transpiration curves.

•Data Analysis: After the experiment is completed, multiple data sets can be analyzed simultaneously, generating color-coded graphs for easy comparison of experimental data.

•Large Screen: The 7-inch highly sensitive touchscreen and user-friendly interface provide users with enhanced data display.

•Data Export: Supports Wi-Fi for wireless data upload and USB flash drive data copying, eliminating the need for plugging and unplugging drivers.

•Cloud Platform Configuration: Test results can be wirelessly transferred to the platform selectively or in batches, facilitating long-term data management and visualization analysis. This also assists scientific research.

•Long Battery Life: A full charge provides 10-12 hours of continuous field use.

•Convenience: Compact and lightweight, it can be carried in a carrying case, making it convenient for individual mobile testing.
