The quartz fiber in a metal protective hose and the front optics withstand up to 150 \u00b0C, while the electronics stay protected outside the hot zone. Accessories such as cooling plate, air purge, 90\u00b0 beam deflection and mounting bracket make integration easy.<\/p>\n<h4 dir=\"ltr\">Free IR-LOG software<\/h4>\n<p dir=\"ltr\">IR-LOG lets you configure all parameters of your pyrometer on your PC and record and archive measurement data. The software is included free of charge. The PC connection uses an interface converter to USB.<\/p>\n<p dir=\"ltr\"><strong>Looking for the right pyrometer?<\/strong><\/p>\n<p dir=\"ltr\">We&#8217;ll find the right solution for your application together.
