Multi-wavelength plug and play pyrometer for Aluminum Applications

A5-EX is a Multi-wavelength plug-and-play pyrometer that uses an application-specific database derived from years of experience in a real application. A5-EX uses special algorithms to calculate the actual temperature and emissivity of the surface accurately. A5-EX can hold multiple databases so that a single instrument can easily switch between applications like Molten metal, Extruded profiles, Rolled aluminum surfaces, Continuous casting, Aluminum billets, Slabs, etc.
It has a laser pointer aligned with the detector, ensuring the laser and detector look in the same spot. This helps precise aiming even at long distances. A5-EX offers Bluetooth communication so that it can communicate with Android smartphones or laptops to view the measured temperature and adjust the parameters/selection of database and data logging.
