KEY FEATURES
• Climate-controlled gas exchange:
Equipped with high-precision CO₂ and H₂O analyzers. The measuring range of the CO₂ analyzer is 0~3100µmol·mol⁻¹, and the H₂O analyzer is 0~75mmol·mol⁻¹. It can precisely regulate the leaf chamber flow rate at 0~1400µmol·s⁻¹. The leaf chamber pressure control range is 0~0.1 kPa with a control resolution of 1.0 Pa. The pressure sensor has a measurement range of -2~2 kPa and a resolution of 1.0 Pa. It also supports precise regulation of leaf chamber humidity from 0 to 90%RH and CO₂ concentration from 0 to 2000µmol·mol⁻¹, providing stable and consistent experimental conditions for reliable gas exchange analysis.
• Advanced chlorophyll fluorescence:
Adopting the pulse-modulated fluorescence technology of Opti-Sciences to measure quantum yield, electron transport rate and various quenching parameters. The instrument modulation frequency covers 1Hz~250kHz, the saturation flash output ranges from 0 to 16000µmol·m⁻²s⁻¹, and the far-red light output ranges from 0 to 20µmol·m1⁻²s⁻¹, which greatly improves the accuracy and application range of fluorescence detection.
• Pre-installed experimental protocols:
Automate key procedures including Laisk, Kok, Yin and Flexas protocols, simplifying complex experiments and ensuring repeatable accuracy.
• White optical LED light source:
Delivers consistent and stable spectral output with light intensity control ranging from 0 to 3000µmol·m⁻²s⁻¹, which is essential for accurate chloroplast migration and non-photochemical quenching measurement.
