Sauermann Kimo Si-TI3 Infra Red Spot Thermometer Contact thermometers aren't always practical — you can't put a probe on an electrically live surface, a moving one, or one that's simply too hot or hard to reach. That's where infrared thermometry comes in, and the Si-TI3 is built to handle exactly these situations. With a measurement range of -40°C to 500°C and a 12:1 distance-to-spot ratio, it measures a target surface from a distance without the reading being skewed by surrounding surfaces. Emissivity can be adjusted to get an accurate reading across different surface materials — genuinely useful when working with shiny metal, painted pipework, or other non-standard surfaces where a fixed emissivity setting would introduce error. A three-line backlit LCD shows infrared temperature, ambient temperature and other useful data simultaneous
