Furnace IR Lens Extender, for 14.5° lens (T198361)

This extender is intended for both fixed and non-fixed lens versions of the GF309 camera. It extends the existing 14.5° lens to achieve a better viewing angle when measuring the temperatures of furnace tubes through viewports.It also features a heat shield to deflect the heat from the furnace. To achieve a high measurement accuracy, the external optics transmission will need to be entered into the camera firmware.
