SF probe stalk flow sensor
Uses: Direct measurement of plant stem flow to determine plant water consumption (transpiration). 4-pin SF-L probe. For trees larger than 20cm in diameter, it is recommended to use a 4-pin probe. Its two auxiliary pins can offset the error caused by the difference in trunk temperature. The 2-pin SF-G probe sensor is used to measure the trunk with a diameter of 7-20cm. It has no auxiliary needle to offset the error caused by the temperature of the trunk itself.
