| Research Abstract |
A simple measuring system for evapotranspiration with an ultrasonic anemometer and fine thermocouple was proposed based on the theory that the temperature measured by sonic anemometer is affected by humidity. In order to reduce the costs of this system, it became necessary to develop low cost amplifier for fine K-thermocouples. Responsibility, separation of noise and accuracy of cold junction has been examined.
