DT100 series TD/Water Level/Tide Recorder adopts imported high-precision titanium pressure sensor and supports both self-recording and online modes of operation. The user can set the data collecting interval of water pressure and temperature, automatically record and store, or directly read the data through cable. With independent high-precision temperature sensor, water temperature data can be recorded while accurately recording the water level. The open-type top protector can be replaced for sampling frequencies up to 16 Hz and can be used for automatic recording of depth and depth profiles.

The DCX-25PVDF self-contained tide gauge is a self-contained tidal level/water level new product that exits according to the characteristics of seawater in China`s seas. It uses a high-precision Hastelloy pressure sensor to provide greater corrosion resistance while maintaining accuracy. At the same time, the outer casing is made of engineering plastic material, which overcomes the shortcomings of the original stainless steel casing which is easy to corrode and rust at the welding place, and better ensures the safety of the internal circuit and the memory.

The CTD48 is a small and handy micro processor controlled multiparameter probe for accurate measurements of pressure, temperature and conductivityThe probe is especially designed for limnological measurements on lakes rivers and estuarys but can be used also in shallow water and in the oceanographic range up to 2000 m depth. The probe is equipped with a 4 channel 16 bit data acquisition system of high long-term stability which meets the  high  precision requirements necessary for oceanographic measurements.

X Series is a family of sensor-Xchangeable oceanographic instruments that allows you to change an instrument’s sensor load in the field and on-demand.With an X•Series instrument andXchangeTM field-swappable sensorheads, your CTD can become an SVTP, shallow range instruments can be made to go deep, and temperature range can be extended or tightened as needed.

When the buoy calculates the original data in the buoy, the true value of each parameter is transmitted back to the receiving station by means of satellite communication, GPRS, VHF radio station and so on. Shore Station Database interface automatically updated display, save. Realize the unmanned, continuous, on-line monitoring integrated marine monitoring platform.

BuoyThe Drifting buoy is composed of buoy body ( sphere), high precision positioning module, data transmission and storage module, monitoring sensor and other components. The buoy body adopts spherical design to reduce the influence of water surface wind.

Bathyswath is a comprehensive bathymetric & seabed mapping survey system, derived from the established & respected SWATHplus system, which became Bathyswath 1. Bathyswath 2 is the latest generation of our bathymetric systems. You will not find lower prices for a similar quality (IHO standards compliant, bathymetry and sidescan).

Our entry level sonar system, combining 450kHz chirped operation with a 1.7° horizontal beam width.

The digitalHyd SR-1 is an autonomous recording device designed for user-friendly operation in underwater acoustic signal acquisition activities. Its compact construction and functionalities allows for the implementation of efficient measurement strategies, thus, avoiding the requirement of large operational human and material resources for deployment and recovery.
