Stack ST769 M6x1 Fluid Temperature Sensors, -20 to 150 degC To suit Stack Dash/Loggers. Used but in full working order ( see photo of Dash displaying Water and Oil Temp ). Recently removed from a Caterham Race Car. I have other parts of the system ( e.g. Dash/Logger, Shift Lights, Beacon Receiver, Download Cable ) - see my other listings.
