Features

1. Equipped with sensors for turbidity, pH, temperature, DO (dissolved oxygen), conductivity, humidity, and pressure.
2. Each movement will be accompanied by the coordinates of the RHEA position.
3. The instrument is designed to be watertight and able to withstand pressure up to a depth of 100 m.
4. Rechargeable 480 Wh Lithium battery.
5. The communication system is available using the iridium satellite (worldwide) and also Radio Wireless Telemetry (local).
6. Data storage media in the form of flash up to 64 GB with .txt storage mode.
7. Ability to adjust the range and display mode of the sonar.
8. Innovation and easy operation, data can be accessed in real-time using a communication system via telemetry using real term software.
9. Microcontroller circuit, high accuracy

ARHEA
Advanced Drifter GPS Oceanography Coverage Area

“An oceanographic parameter measurement instrument equipped with diving capabilities and depth settings capable of providing high-quality data and capable of data acquisition in operations at depths of the water column”

Features

1. Ability to dive and measure oceanographic parameters based on the depth of the water column
2. Equipped with sensors for turbidity, pH, temperature, DO (dissolved oxygen), conductivity, and depth.
3. The communication system is available using the iridium satellite (worldwide) and also Radio Wireless Telemetry (local).
4. Data storage media in the form of flash up to 64 GB with .txt storage mode. Ability to adjust the range and display mode of the sonar.
5. Microcontroller circuit, high accuracy.
6. Equipped with propulsion in the form of thrusters and static fins that can control the depth and use of an altimeter for obstacle avoidance.
7. Several configuration options are possible: altimeter configuration will detect the desired distance from the bottom of the water, ARHEA timeout configuration, if ARHEA is already at a depth of > 100 meters it will immediately enter timeout mode and will rise to the surface automatically, amount of data to be sent to the satellite, ARHEA delay time configuration again diving, and ARHEA mode configuration
