Usually, the pyrometer is mounted on a control panel. Alternatively, the pyrometer is attached to a suitable flat surface at a height that is convenient for viewing. Install the scanner so that the display is not in direct sunlight.
The operational temperature range of the display is −20 to 75 °C (−4 to 167 °F).
