Portable Photosynthesis Meter IN-GH2
Product features
Intelligent Interaction: Equipped with an Android smart operating system and a highly sensitive touchscreen, it provides an intuitive human-computer interaction interface, real-time display of the measurement process, and a smooth operating experience.
Stable and Precise: Employing dual-wavelength infrared CO₂ analysis technology, combined with temperature regulation and atmospheric pressure measurement units, significantly improves the stability and accuracy of CO₂ measurements, effectively suppressing numerical drift caused by temperature fluctuations.
Comprehensive Functionality: Capable of simultaneously acquiring core photosynthetic indicators such as photosynthetic rate, transpiration rate, intercellular CO₂ concentration, stomatal conductance, and water use efficiency, as well as environmental data such as CO₂ concentration, humidity, radiation, temperature, and pressure.
Highly Customizable: Supports user-defined experimental annotations and allows real-time display and analysis of Pn curves, Tr curves, light-photosynthesis curves, and humidity-transpiration curves.
Professional Data Analysis: Supports comparative analysis of multiple data sets after experiments, automatically generating color-coded graphs for easy result comparison and research.
Large Screen Display: Equipped with a 7-inch high-sensitivity touchscreen, featuring a user-friendly interface and clear, intuitive data display.
Convenient Data Export: Supports Wi-Fi wireless data transfer and direct data copying via USB flash drive; plug and play, no driver installation required.
Cloud platform support: Data can be selectively or in batches wirelessly transmitted to a cloud platform, facilitating long-term data management, in-depth analysis, and visualization to support scientific research decision-making.
Long battery life: Built-in high-performance lithium battery supports 10-12 hours of continuous fieldwork on a full charge.
Portable design: The instrument is compact and lightweight, and comes with a dedicated carrying case for easy carrying by a single person for mobile measurements.
