Advantages of the Handheld measuring device XC250 (with pyrometer)



Lufft has expanded the X generation of handheld measuring devices with the new XC(ellent) series. Both the XC200 and the XC250 devices measure values ​​such as temperature and relative humidity with extremely high levels of precision. Temperatures can be measured either with the fixed sensor or contact-free with the integrated pyrometer.


Two powerful and compact handheld instruments that offer a modern and especially robust design: the XC series. Measurement results are easily read via the large digits on the high-contrast and colorful display.


The XC series handheld measuring devices can be used individually and are particularly suitable for detecting moisture problems. Masonry in all kinds of buildings can be checked for wetness and moisture by combining temperature and relative humidity readings with the surface temperature.

Examples of the Hand-held measuring device XC250 (with pyrometer)

You can always rely on both the XC200 and the XC250 hand-held measuring devices—even at extreme temperatures, they easily collect physical data such as temperature, absolute humidity and dew point.

In developing the XC-Series, we were primarily focused on the needs of those engaged in climate monitoring, climate assessment and climate control. As a result, the XC200 and the XC250 are particularly suitable for climate management in buildings, museums, storage rooms and electrical and IT cabinets. Naturally, it is also valuable in other fields—anywhere the measurement of such data is necessary.
