D270

single beam echosounder

D270 is a portable, single-beam echosounder that integrates a built-in water temperature sensor to enable real-time sound velocity correction in response to temperature changes, resulting in superior depth measurement accuracy. The D270 echosounder is a cost-effective solution for various applications, including river cross-section measurements, reservoir capacity assessments, and dredging volume analysis. Operating on a Linux platform, the D270 features intuitive web-based parameter configuration and seamless chart plotting, simplifying survey tasks and improving efficiency. With 8GB of internal memory, it provides ample data storage for even the most extensive bathymetric surveys.

Description

VERSATILE SINGLE BEAM ECHO SOUNDER

he D270 is a complete package consisting of the D270 controller, a transducer with built-in temperature probe, and its mounting mast. Operating at a frequency of 200 kHz, the D270 provides a maximum depth measurement capability of 200 meters. Its wireless connection to an optional GNSS RTK receiver is ideal for high accuracy bathymetric surveys. The D270 is particularly well suited for river cross-section surveys and reservoir capacity assessments.

INFORMATION AT A GLANCE

The D270's OLED display provides a quick and comprehensive overview of vital data, including voltage status, water depth, and GNSS satellite tracking. Users can easily switch to view additional information such as water temperature, sound velocity, and draft, making it a versatile and user-friendly way to monitor operations effectively.

GREATER CONVENIENCE AND EFFICIENCY

Bluetooth and Wi-Fi connectivity enhances both convenience and efficiency by enabling wireless setup when used with an optional GNSS receiver. Integrated connectivity streamlines wireless communication and data transfer, increasing workflow efficiency and ensuring seamless bathymetric surveying operations.

ENHANCED OPERATIONAL SAFETY

By giving operators immediate alerts of shallow water and data anomalies, the D270 significantly improves operational safety. Its proactive workflow ensures safe operation and reliable results when conducting bathymetric surveys, even in challenging environments.
