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.

A low cost, lightweight alternative to larger flow meters, ideal for use in applications where the superior durability and depth rating of Valeport`s larger meters is not necessary. Utilising the standard Vaieport 125mm diameter impeller, the Model 106 features speed and direction parameters as standard, with further options of temperature and depth.

The StreamPro ADC Prevolutionizes discharge and velocity measurement in stream from 15-200 cm indepth. Its bottom tracking capability provides the ability tomove continuously across the stream to obtain a discharge measurement in two orthree minutes instead of thirty minutes to an hour using the olderpoint-by-point method.

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 tiahtened as needed.

The InsiteIG Portable Meter is a unique instrument that combines advanced electronics with exceptional functionality and ease of use. The meter will accept any standard portable DO, SS, pH, or ORP sensor and will automatically configure itself for the correct operation. The quick-disconnect, mil-spec connectors allow for quick sensor swaps. The meter includes a 250 point data logger that records sensor type, sensor reading, date, time, and location. The included Portalog software offers several sort options to customize the downloading and reporting of collected data. The rechargeable batteries allow for 8+ hours of use between charges.

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. The combination of ultra low power design circuit and solar charging board greatly prolongs its working online time. Its internal integrated flash LED light emitting lamp is convenient for night recycling. Drifting buoy built-in high-capacity data storage card, to ensure no loss of data at the same time, while the magnetic switch is designed to increase water tightness. 

The Bathy 500 HD is a state-of-the-artelectronic survey instrument used to generate precision chart recordings anddigital data output. Low power consumption, portability, ease of use, ruggedconstruction, and built in communication interfaces for navigation/data loggingdevices make the Bathy 500 HD the ideal solution for shipboard surveys.

The HydroBox HD is a portable high-resolution, shallow water echo sounder. It is designed exclusively for inshore and coastal hydrographic marine surveys up to 1000 meters of water depth. Available in single frequency or simultaneous dual frequency models
