A small sensor that measures the temperature of leaves on the Unipos website Leaf temperature sensor (LT-1T) Page has been added.
The Leaf temperature sensor (LT-1T) is an ultra-compact touch probe that measures the thermodynamic temperature (absolute temperature) of plant leaves.The small clip-type probe that holds the leaves in between and its special design enable measurement of natural leaf temperature with almost no disturbance.
The lightweight stainless wire clip contains a precision glass-sealed thermistor with a diameter of approximately 1 mm, and the thermistor and wire clip are connected by a thin 0.15 mm lead to minimize heat conduction and response time. It has been.In addition, a waterproof signal conditioner is connected to the tip of the probe.
