This is a high-speed and high-precision two-color radiation thermometer that combines the latest two-color technology with digital signal processing! (Made by Sensortherm, Germany)

The Metis series is less affected by emissivity and can accurately measure temperature even when the view is obstructed by smoke or viewport dirt. ■Features of the Metis Series - Two-color calculation can be performed with just 2% infrared energy - Temperature measurement possible from 250°C - High-speed response (1msec or 80μsec) & small spot diameter (minimum φ0.8mm) achieved ■Applications - Temperature measurement inside furnaces through dirty windows - Temperature measurement in the steel industry with large amounts of steam and smoke - Temperature measurement of fine wires in the wire drawing process ■High-performance Software (Included) - Simultaneous measurement and graphing in "two-color thermometer mode" and "single-color thermometer mode" - Can also measure radiation signal intensity, allowing for a simple measurement of the workpiece's emissivity ★ We are currently running a free demo unit loan campaign. Please take this opportunity to try it out!
