An apparatus and method for measuring coolant temperature to ensure the proper amount of coolant for refilling or servicing a coolant system, such as an automobile coolant system, are disclosed. In one embodiment, the apparatus includes a measurement display for viewing the temperature of air conditioning output inside a vehicle while the user is outside the vehicle refilling or servicing a coolant system. The measurement display is in communications with a temperature sensor measuring the air temperature at a vent inside the vehicle to allow a user to ensure the proper amount of coolant is refilled.

A temperature sensor assembly for measuring a gas temperature in a gas flow stream includes a first substrate having a first surface configured to be connected to a thermally conductive structure in a gas path, a first temperature sensor mounted to the first substrate a first distance from the first surface, and a second temperature sensor mounted to the first substrate a second distance from the first surface.
