Catalog excerpts

testo 835 - fast, accurate infrared measuring instruments Measure safely and accurately even at high temperatures 4-point laser shows the exact measuring range, preventing incorrect measurements Safe measurements from a long distance, thanks to 50:1 Integrated emissivity measurement for absolute measuring Patented surface moisture measurement (testo 835-H1) Convenient menu guidance with icons and joystick Measuring value and location memory, and data analysis on Take advantage of the benefits the testo 835 series has to offer, in virtually all sectors of trade and industry: e.g. monitoring wall temperature and humidity, inspecting air conditioning and ventilation systems, the maintenance of industrial systems or the quality control of industrially manufactured products. Testo infrared measuring technology, which delivers first- class results even at long distance, is particularly helpful when monitoring the temperature of objects that are small, moving, difficult to access or extremely hot. The many features increase the room for manoeuvre, for example in the building trade when carrying out surface moisture measurement via infrared, or in the metal, glass and ceramics industry when measuring temperatures up to 1500 °C. So you can be certain of having everything under control and of safeguarding your standards of quality at all
