MWx-AB - Aluminum Billets

MWx technology accurately measures high temperature billets where MW technology falls short. MWx pyrometer only works when looking at the side of the billet. No specific algorithm or offset is required – MWx-AB works across all alloys. Pyrometer output is set for 400-1100°F (200-600°C), but will only measure temperatures down to 575°F/300°C.
