34Non-contact temperature measurement on large surfaces (10:1 optics)testo 830-T1testo 830-T4The fast infrared thermometerwith 1-point laser sighting. The10:1 optics are ideal fortemperature measurements onlarge surfaces• 10:1 optics• Display of current value andHold valueThe versatile infrared thermomterwith 30:1 optics allowstemperature measurement at asafe distance from themeasurement object. Thediameter of the measurementpoint at a distance of 1 m is only3.6 cm. The 2-point laser sightingavoids the measurement ofundesired areas outside themeasurement object.testo 830-T4: Emissivitydetermination withexternal temperatureprobe• Emissivity adjustable from 0.2to 1.0Additional benefits:• Audible and optical alarm whenlimit values are exceeded• Fast measurement valuerecording at two measurementsper second• 30:1 optics for measuringtemperature at a distance, evenon small objects• 2-point laser for spot sightingLarge, backlit displayNon-contact temperature monitoring on a pipe withtesto 830-T4.
