Inverted thermometer, deepwater thermometer

SWJ-73 is a hydrological measurement instrument used to measure water temperature at any depth within 40 meters in rivers, lakes, reservoirs, runoff testing stations, etc. The measurement range is between -2 ℃ and+40 ℃. It can also be used for sampling water pollution in rivers, lakes, and storage areas. The national standard GB13195-91 "Determination of water quality and temperature using thermometers or inverted thermometers" specifies measuring instruments.
