    This depends on the thermistor. If they use the default Semitec 103AT, the linearization polynomial that the gauge uses shows this performance (top&bottom lines are for typical thermistor tolerances for the 103AT):

    So this is analyzed up to 110 deg.C (which is what we use as the max. temperature)
