Product overview
The Marathon MM series platform consists of five IR temperature sensor models, each with a measurement wavelength and temperature range appropriate for specific application needs, from low temperature plastic processing to high temperature glass and metals processing.
The Marathon MM features Precision Variable Focus that allows fast, easy and accurate adjustment of the focus of measurement targets, either by push-button at the rear of the instrument or remotely via an RS232/RS485 PC connection, where adjustments can be seen in real-time through video. Sensors with variable focus option can be configured according to specific application requirements, reducing the installation time and chance for incorrect installation.
All sensors feature identical installation hardware and include Raytek DataTemp Multidrop software to enable easy and consistent installation, configuration and data capture across the full breadth of an applications.
