| Marine Guardian CTD is an indispensable tool for measuring basic physical elements of water. It can be used both in sea water and fresh water.The basic parameters for instrument measurement include conductivity, pressure (depth) and temperature, through which salinity and density can be calculated.Its integrated sensors (temperature, conductivity, pressure) are all intelligent sensors that can be automatically detected and identified.Among them, the conductivity sensor adopts the inductive measurement principle, so it is not easily contaminated and damaged when used for long-term monitoring; the temperature sensor 4880/4060 adopts the thermistor bridge principle; the pressure sensor 4646/4117 adopts the quartz piezoresistive bridge principle. | ||||||||||
| Marine Guardian CTD is mainly used for long-term continuous monitoring of salinity, temperature and depth.Application areas include nearshore monitoring, climate research and aquatic products.The Marine Guardian CTD can also be used as a multi-parameter platform for measurement of other parameters. | ||||||||||
| Ocean Guard CTD can be collected through Andra's real-time digital acquisition software, and the output parameters can be displayed and processed through SeaGuard Studio software, where salinity, density, sound velocity and depth are calculated by SeaGuard Studio software. | ||||||||||
