Met/Hydro Monitoring Buoy

Long-term monitoring of meteorological and hydrological conditions in the bay and collect data over a long period of time. Buoys are designed to enhance the efficiency and safety of maintenance work.

GPS Wave Measurement Buoy

A small, lightweight yet highly accurate drifting buoy that can monitor waves (wave height and direction) for more than 6 months using solar power system.

Water Temperature Monitoring Buoy

This monitoring buoy is based on Zeni Lite's popular 10-PS model and capable of measuring the water temperature of any three layers of water.

Simple Water Temperature Monitoring Device

Suitable to be mounted on buoys and rafts, the system can measure multiple layer water temperatures to a depth of 50m. Consists of a water temperature sensor, communication terminal and power supply.

GPS Wave Measurement System

Thia GPS Wave measurement system can be installed in an existing buoy and wave data (wave height, wave direction, period) can be measured. LPWA or satellite communication methods are available.

Water Temperature Monitoring Buoy

Equipped with a water temperature sensor and a low-power telemeter device, Zeni Lite monitoring buoy observe the water temperature in aquaculture fishing grounds.

GPS Wave Measurement Buoy

Zeni Lite GPS Wave Measurement Buoys monitors wave height, direction and period using a single positioning GPS. Buoy designs are customized to suit the conditions of the installation sites.

Thermal Discharge Monitoring Buoy

High precision monitoring of thermal discharge temperature from electric power facilities. Spar type or cylindrical type buoys are available depending on the installation conditions.

Oil Slick Monitoring Buoy

This monitoring buoy detects oil floating in the sea and constantly observes marine pollution. The oil film detection methods of laser type, electrode type, and UV fluorescence method are available.

Water Quality Monitoring Buoy

A small, lightweight, general-purpose buoy that can be easily installed and retrieved by human power in a short period of time. It is ideal for relatively calm waters in the bay.

Current Monitoring Buoy

This buoy monitors the current direction and speed in the harbor at a fixed point. Zeni Lite can propose the optimal buoy to suit the site conditions as well as the contents of observations.

Weather Observation Buoy

High-wave resistant buoys for long-term weather, wave monitoring in the open sea, equipped with lithium batteries last for one year.

Monitoring Buoys for Dams and Lakes

Monitoring buoys for dams, reservoirs, lakes. Designed to be adopted to special installation conditions such as water level fluctuation, freezing, acidic water, etc.
