Pyrometer optris CSmicro 3M for temperature measurement of metals
The pyrometer optris CSmicro 3M has been designed for a temperature range from 50°C to 600°C (122 to 1112 °F). Its special spectral range of 2.3 µm makes it the ideal IR pyrometer for temperature measurement of metallic surfaces starting from 50°C (122 °F) and it allows for measurements through glass.
The small infrared measuring head is optimally suited for installation in limited spaces and subsequently makes possible an especially cost-efficient mechanical process integration.
New: 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.

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 on makes the temperature sensor a favored measurement tool for all sorts of low-temperature measurement of metals.
