Non-contact temperature measurement on large surfaces (10:1 optics)
testo 830-T1 testo 830-T4
The fast infrared thermometerwith 1-point laser sighting. The
10:1 optics are ideal for
temperature measurements onlarge surfaces The versatile infrared thermomterwith 30:1 optics allows
temperature measurement at a
safe distance from themeasurement object. Thediameter of the measurement
point at a distance of 1 m is only
3.6 cm. The 2-point laser sighting
avoids the measurement of
undesired areas outside the
measurement object. •10:1 optics•Display of current value andHold value•Emissivity adjustable from 0.2to 1.0•Audible and optical alarm whenlimit values are exceeded•Fast measurement valuerecording at two measurements
per second Additional benefits: •30:1 optics for measuringtemperature at a distance, even
on small objects•2-point laser for spot sighting
Large, backlit display Non-contact temperature monitoring on a pipe withtesto 830-T4. Two laser beams mark the measurement
