Emissivity calculator

The correct emissivity to be set on the pyrometer is calculated from the measured value displayed on the pyrometer, the true object temperature, the emissivity preset at the pyrometer and the ambient temperature (required for some instrument types).
The value displayed by the pyrometer is calculated from the true object temperature, the emissivity of the measurement object, the emissivity set on the pyrometer and the ambient temperature (required for some instrument types).
