Conductivity & Temperature Recorder
It consists of a “7-electrode conductivity sensor” with an integrated temperature sensor. The temperature sensor is very stable and consists of a fast response and highly reliable thermistor. The conductivity sensor has both ends of the conductivity cell ending with same polarity, which results in no electric current flowing through the external side of the sensor and eliminates external influence. The compact design, with infra-red communication and titanium pressure-resistant case ensures a robust structure resistant to corrosion and humidity, which allows the instrument to be deployed in a variety of sites and conditions.
PAR (Photosynthetic Active Radiation) Logger
High-precision pocket-size light intensity logger for long-term observations. (maximum 573 days for 1 minute interval observation). The cosine correction allows the sensor to have an excellent spectral sensitivity even when the light source is not directly above the sensor. Also, AAA alkaline batteries used which are locally available around the world, reducing the operating costs.
High-precision pocket size water temperature logger for long-term observations. (maximum of 573 days for 1 minute interval observation). The reduced size allows the device to be installed in large numbers in a single mooring system, allowing investigating temperature fluctuations at increased spatial resolution. Also, AAA alkaline batteries used which are locally available around the world, reducing the operating costs.
Pressure Logger (Depth Meter)
High-precision pocket-size pressure logger (depth meter) for long-term observations. These pocket-size pressure loggers (depth meters) are suitable for long-term observations (maximum of 573 days and 52 days respectively with 1 minute interval observation). These two loggers can be attached to fishing nets, underwater instruments and moorings. AAA alkaline batteries used are locally available around the world, reducing the operating costs.
