Product Overview

Airmar HT200 Smart Hi-Precision Temperature Sensor

Model: HT200BV-N2

  • High-precision water temperature sensing for quick reporting
  • Low-profile design extends only 5 mm (3/16") outside the hull
  • Retractable insert for easy cleaning, even while in water
  • NMEA 2000 certified for seamless integration

When fishing in blue waters or tidal estuaries, identifying temperature breaks is crucial for locating fish. The HT200 features a large surface area for a rapid 0.15-second response to water temperature changes. Overlay the temperature data on your nautical chart or sounder to watch for critical changes and fish strikes. Marking the boundary between hot and cold waters ensures a successful fishing trip!

Airmar's Smart Sensors include embedded microelectronics with the temperature sensor and signal processor situated only millimeters apart. The signal is processed within the housing, requiring only a single cable to connect to an NMEA 2000 network for temperature data collection.

Expert Overview

The Airmar HT200BV-N2 is a dedicated water temperature sensor designed for integration into NMEA 2000 networks. This thru-hull unit provides high-precision temperature data with a rapid 0.15-second response time to changes in water conditions. Its low-profile design extends only 5 mm outside the hull, minimizing drag. The sensor features a retractable insert, allowing for maintenance and cleaning without dry-docking the vessel. Embedded microelectronics process the temperature signal directly within the housing, simplifying installation to a single cable connection to an existing NMEA 2000 network. This device is suitable for commercial fishing operations or marine research where accurate and timely water temperature monitoring is essential for identifying thermal breaks or environmental analysis.
