QT-2021 pin plant stem flow system

Product Details

QT-2021 pin plant stem flow system uses advanced technology to measure the stem flow to obtain the water consumption of the plant. The energy balance probe measures the heat carried by the stem stream into a real-time stem stream in g / .s or Kg / h. And because it is usually heated by only 1 ° C to 5 ° C, it is harmless to crops. The principle of energy balance has been scientifically proven and available data show that it is effective for most crops and many tree species. The stem flow probe does not need to be calibrated because the stem flux is directly determined by the energy balance and the thermal conversion rate of the stem flow.
