Marathon MM 3M infrared sensor

The Marathon MM 3M infrared sensor uses shorter IR wavelengths to minimize errors due to the uncertainty of emissivity. This makes it less sensitive to changes in emissivity on the target material than long-wavelength sensors and enables it to provide more accurate readings across multiple targets at varying temperatures. The sensor features precision variable-focus optics that allow it to be accurately focused with a touch of a button, and a NEMA-4 sealed user interface that guarantees the integrity of the electronics. The 3M is the latest addition to the Marathon MM Series, which includes six models that cover the ranges of –40°C to 800°C (low), 250°C to 1,100°C (medium), and 300°C to 3,000°C (high). All of the units provide enhanced continuous remote temperature monitoring, ease of installation and sighting, video surveillance and documentation, remote PC interface, flexible configuration, and field calibration software.
