| Abstract: | An instrument to measure the profile temperature of water surface and water body is developed. The design principle, structure, testing process and final experimental result of the instrument are expounded. The water body temperature thermometer integrates the radiation temperature measurement and the contact temperature measurement, and can measure the temperature of the water body at different positions between the depth 1200mm below the surface of the water. The temperature range is 0～40℃ which the uncertainty of the radiation thermometers and the contact thermometers are 0.24K and 0.12K, respectively. The instrument has the function of automatically storing data, and also can be floated on the water surface continuous automatic measurement in two weeks. |
| Keywords: | metrology temperature measuring instrument water surface water profile contact temperature measurement radiation temperature measurement |
