AIRMAR ST850 P17 Smart Speed and Temperature Sensor Thru-hull Plastic

The ST850 is a low-profile, retractable, thru-hull sensor that computes accurate speed and temperature data and sends it to any NMEA 0183 or NMEA 2000® display or network. These low-profile units are nearly flush and minimize drag with only 5 mm (3/16 in.) extending outside of the hull. The housing features a water valve which minimizes water ingress into the boat when the retractable insert is being replaced with the blanking plug.

Airmar Smart™ Sensors have embedded microelectronics. The signals from the speed and temperature sensors are processed right inside the housing itself. All that is needed to receive speed and temperature data is a single cable into a compatible network or display. Available as an analog sensor or a digital Smart Sensor that can output in NMEA 0183 or NMEA 2000 standard.
