The present invention pertains to a thermometer. More specifically, a thermometer for measuring the temperature of a cylinder exhaust gas of an internal combustion engine for a ship includes: a first sensor rod for sensing temperature; a mechanical temperature measuring sensor coupled with the first sensor rod and having a temperature display indicating measured temperature; a second sensor rod inserted into the first sensor rod; an electric temperature measuring sensor formed at the upper portion of the second sensor rod and having a port to be connected to the outside; and a PID compensating circuit connected to the port so as to compensate temperature. |
