It measures relative humidity, air temperature, dew point and specific humidity, reads surface temperature by infrared or contact probe, and shows how close a surface is to dew point. It also logs unattended at intervals from one minute to 24 hours and downloads to PC software.\u003c\/p\u003e\n\u003cp\u003eThis kit adds a plug-in surface temperature probe to the instrument, which is what you need to compare surface temperature against dew point reliably on glass, gloss paint, polished tile and other low-emissivity surfaces where the infrared reading is less dependable.
