Areas of application for the pyrometer optris CSmicro 3M

The compact IR thermometer optris CSmicro 3M has a measuring wave length of 2.3 µm and is therefore used for temperature measurement of metallic surfaces and composite materials in processing operations. Especially its low temperature range from 50°C (122 °F) on makes the temperature sensor a favored measurement tool for all sorts of low-temperature measurement of metals.

IR mobile App for Android devices

With IR mobile you are able to monitor and analyze your infrared temperature measurement on a connected smartphone or tablet. The app works on most Android devices running 4.4+ with a micro USB port supporting USB-OTG (On The Go).
