Photosynthesis detector

Introduction:

HM-GH2 Plant Photosynthesis Meter is an experimental instrument for detecting photosynthesis of living leaves of plants in artificial climate chambers, greenhouses, sheds, fields, etc. The measurement content includes air CO2 concentration, environmental 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), respiratory rate (Rd), transpiration ratio (TR), a total of 15 parameters, which can be used for scientific research such as plant growth physiology, photosynthetic physiology, and stress physiology. The plant photosynthesis meter is suitable for agricultural research, teaching, gardening, grass industry, forestry and a wider range of fields.

Product Features:

Intelligent: Using Android operating system, high-sensitivity touch screen. Efficient human-computer interaction, real-time display of the measurement process, better operating experience;

High stability: dual-wavelength infrared carbon dioxide analyzer, adding temperature regulation and atmospheric pressure measurement unit, effectively improves the stability and accuracy of carbon dioxide. It effectively avoids the drawback of excessive fluctuations in carbon dioxide values due to temperature changes;

Multi-function: It simultaneously measures photosynthetic rate, transpiration rate, intercellular carbon dioxide concentration, stomatal conductance and water use efficiency, as well as carbon dioxide concentration, relative humidity, photosynthetically active radiation and air temperature, leaf temperature, atmospheric pressure and other indicators;

Customization: Users can customize and edit experimental notes according to measurement needs, and can display Pn curve, Tr curve, light-photosynthesis curve and humidity-transpiration curve;

Data analysis: After the experiment is completed, multiple sets of data can be analyzed at the same time to generate curves with different colors, which is convenient for experimental data comparison;

Data export: It supports wifi and Bluetooth transmission, and data can be uploaded wirelessly; it also supports USB copying of data, without driver plugging and unplugging.

Configure cloud platform: The test results can be selectively or batched wirelessly transmitted to the platform, which is convenient for users to conduct long-term data management and visual analysis. Assist scientific research.

Long battery life: It can be used continuously in the field for 10-12 hours when fully charged.

Convenience: small size, light weight, can be carried with a suitcase, convenient for single-person mobile testing;
