Product introduction:
HLY-GH5 is the third generation photosynthesis instrument developed by our company. This photosynthesis instrument not only has open circuit measurement and closed circuit measurement modes, but also adds light response curve measurement and curve measurement modes; At the same time, temperature and air pressure compensation functions have been added, so that the instrument does not require the operator to constantly adjust the knob during use. The flow rate can be adjusted between 200-900umol/s, and there is no need for the operator to manually switch between various measurement modes. The instrument can automatically recognize and switch according to the measurement mode set by the user, avoiding measurement errors caused by the mode switch not being in the normal position. HLY-GH5 adopts high-definition color screen display, which can clearly observe the data changes on the display screen even in direct sunlight.

Features:
1. It has four modes: open circuit measurement, closed circuit measurement, curve measurement, and PAR response curve measurement;
2. Each measurement mode can be automatically switched according to user settings;
3. Users can choose to use TF card storage or USB flash drive as storage media, with a storage capacity of 32GB and expandable up to 64GB;
4. Adopting a micro electronic flowmeter, the flow rate can be adjusted within the range of 200-900umol/s, and it also has an air path blockage alarm prompt function to avoid testing errors and pump damage caused by air path blockage;
5. Adopting dual humidity sensing modules and placing them at the head of the measuring handle can quickly respond to changes in humidity inside the leaf chamber, avoiding air path delays. Make the testing and calculation of transpiration rate and stomatal conductance more accurate and rapid;
6. The device can automatically recognize the connection status of each unit and provide corresponding prompts.
