ST850 Speed and Temperature Sensor Bronze Thru-hull Analog
Part NumberST850B-A
The ST850/800 is an analog, retractable speed and temperature sensor. The sensor fits inside a low profile bronze thru hull housing that is nearly flush to the hull, with only 5 mm (3/16”) extending outside of the hull. The housing has a valve assembly that helps to minimize water ingress in the bilge when the sensor is removed for routine maintenance of the paddlewheel.
