Plant respiration detector

Instrument usage:

The BK-ZH10 plant respiration meter is used to measure the respiration rate and photosynthetic rate of plants, and is suitable for scientific research and teaching in botany and ecology. At the same time, it has broad prospects for development and utilization in many professional experiments such as biology, agriculture, horticulture, forestry, insects, microbiology, and animals.

Product Features:

1. The selected microcontroller automatically collects and processes various signals that change during the measurement process, and is equipped with a 3.5-inch TFT true color LCD screen color display, which can achieve menu style display of multiple information and simple operation under cursor guidance; Using 16GB of memory, it can store more data, with a storage capacity of several million sets for field measurement data.

2. This instrument is small in size and light in weight, can be carried around, operated by a single person, and can be moved freely. The air and circuit connections are clear, and the operation and measurement methods are very convenient. When measuring, it is very easy to unload the blades.

3. Excellent performance: The stability, accuracy, importance, and time response of the measurement are all very good, and it can also measure plant physiological parameters such as photosynthetic rate (PN), carbon dioxide concentration (CO2), photosynthetically active radiation (PAR), temperature (T), and plant respiration rate.

Measurement indicators:

CO2 concentration

Leaf temperature

Photon concentration (photosynthetically active radiation)

Leaf chamber temperature

Leaf chamber humidity

Leaf photosynthetic rate
