SD208 basic thermohaline deep water meter can measure,calculate and record the seawater conductivity / salinity,temperature, depth (pressure) and sound velocity (waterdensity) and other parameters. According to the needs of the user, the instrument can also be equipped withdissolved oxygen, fluorescence and turbidity of threeparameter sensor. After measuring, physical memory, data is recorded on the instrument was built, and can be easilytransmitted to the computer, the user can immediately see the results. Equipment SD200W software, not only can be used for data transmission, but also has the powerful dataprocessing function. This makes SD204 performance comparable to that of some large, expensive STD system.SD208 can also be used for online real-time monitoring bycable, telephone lines or satellite.

Through the vacuum forming technology of electronic components, instruments and other components in high strength poly Yaan ester casing, to ensure that theinstrument has good water resistance.

Instrument switch consists of a magnetic button or thecomputer keyboard to control. C type battery accommodating two replaceable battery module, instrument and electrical energy consumption is very low, under normal operation, the battery capacity can maintainequipment continuous working for a year.
