The PlantECG fluorymeter is a portable, non-invasive device designed to measure chlorophyll fluorescence in plants. It provides rapid assessment of plant physiological status and stress detection by analyzing how plants emit fluorescence when exposed to light pulses.
For best results, allow the plant leaf to dark-adapt for 20-30 minutes before measurement. This resets the photosystem and provides a baseline measurement. You can use the proper dark adaptation chamber or simply cover the leaf area with a cloth.
Carefully position the leaf clip on a leaf. Ensure good contact between the measurement head and the leaf surface. Avoid damaged or diseased areas.
Press the measurement button. The device will emit a light pulse and record the fluorescence response. The measurement typically takes 1 seconds. Do not move the device or leaf during measurement.
The device will store the measurement data automatically. Note the environmental conditions and any observations about the plant's condition.
The device measures the O-J-I-P fluorescence induction curve, which captures the photosynthetic response over microseconds to milliseconds:
The fluorymeter exports data as CSV files containing the complete fluorescence induction curve with 118 data points. These files can be uploaded to the PlantECG Analyzer for detailed parameter calculations and visualization.
CSV File Format: Each file contains time values (in milliseconds) in the first row, followed by fluorescence intensity values. Multiple measurements can be included in a single file for batch processing and averaging.
The device contains the following elements:
If measurements show unexpectedly low fluorescence values, check that:
