For a reliable testo 830-T1 surface-temperature check, set emissivity appropriately, measure an area larger than the instrument’s 10:1 optical spot and avoid shiny or reflected backgrounds. The laser identifies.
The testo 810 combines a non-contact infrared surface-temperature reading with an integrated air-temperature measurement. Select a suitable matte target, keep the measured area inside the 6:1 optical spot , all.
To inspect building moisture with the testo 606-1 , select the correct material characteristic curve, press both pin electrodes into the material as instructed and compare measurements at several equivalent loc.
Place the testo 608-H1 in the room to monitor air temperature, relative humidity and displayed dew point over time. Compare the dew point with separately measured wall-surface temperatures when dampness appears.
Use the testo 625 to measure room-air temperature and relative humidity and read the calculated dew point. Then measure the suspect wall’s surface temperature with a separate suitable instrument . If the surfac.
To assess workplace thermal comfort with the testo 480 , use compatible probes to record air temperature, relative humidity, air speed and globe temperature, then select the instrument’s PMV/PPD measurement pro.
