The Optris CSmicro LT / LTH Thermometer features a miniaturized stainless steel measuring head that is suited for installation in limited spaces. The size and its temperature resistance up to 356°F (180°C) make the mechanic integration of the measuring head especially cost-efficient.

The LED display works as an alarm signal, target support, temperature-code display and self-diagnosis. The electric components inside the cable allow for high temperature resistance of the measuring head.

The CSmicro series can now be operated via the new IR mobile App (Android). The App enables to monitor and analyze infrared temperature measurements on a connected smartphone or tablet.
