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.

基于声波风速计测量温度受湿度影响的原理，提出了一种简单的超声波风速计和精密热电偶蒸散量测量系统。为了降低该系统的成本，有必要开发用于精细 K 热电偶的低成本放大器。对冷端的责任、噪声分离和精度进行了检查。
