IR Tempreture Sensor with GIGE (Manual Focus)


The FLIR A35 is a thermal imaging temperature sensor for condition monitoring, process control/quality assurance, and fire prevention applications. The A35 integrates seamlessly into existing systems, offering comprehensive visual temperature monitoring. As part of the Ax5-Series, the A35 is among the only thermal imaging temperature sensors on the market to provide temperature linear output through GenICam™ compliant software.
