JJF 2105-2024 《Calibration Specification for Seawater Temperature and Salinity Measuring Instruments》 Related products

JJF 2105-2024 "Specification for calibrating sea water temperature and salt measurement instrument" is applicable to the calibrating work of sea water temperature and salt measurement instrument and its independent temperature measurement Sensors, salinity measurement Sensors. This specification refers to the JJG 763-2019 standard on temperature and salt depth measurement instrument. Sea water temperature and salt measurement instrument is an important equipment for the measurement of sea water temperature and salinity, and is widely used in marine scientific research and marine environment monitoring. The temperature and salt instrument is connected to the host through a water-tight connector to realize real-time continuous measurement of sea water temperature and salinity data. The working principle includes the use of thermistors or Miscellaneous Sensors to measure water temperature, the use of conductivity Sensors to measure salinity, and the processing of data through analog-to-digital converters and microcontrollers. Finally, the salinity and temperature values are calculated and output according to the PSS-78 salt standard formula. This specification determines the accuracy and Reliability of the insulation salt measurement instrument under different environment conditions to meet the needs of marine science and engineering applications.
