Speed - temperature transducer for boat (thru-hull) ST800
Airmar
The ST800 speed and temperature sensor processes a digital signal inside the housing. Then this Smart™ Sensor sends the data to a chart plotter, radar screen, or digital display in either analog or NMEA 2000® formats. The plastic P120, bronze B120, and stainless steel SS520 housing options are available to meet most hull requirements. These low-profile units are nearly flush and minimize drag with only 5 mm (3/16") extending outside of the hull.
