Sauermann Kimo K-Si-TI3 Infra Red Spot Thermometer Contact thermometers just aren't up to the job in lots of situations. You can't stick a probe into an electrically live surface, or one that's moving, or just plain bloody hot. Or what about when the surface is simply too hard to get to? That's where infrared thermometry comes in - and the K-Si-TI3 is built to handle all these kind of tricky situations in one neat package. With a wide measurement range of -40°C to 500°C and a useful 12:1 distance-to-spot ratio, you can measure a target surface from a distance without worrying that the reading is going to be skewed by surrounding surfaces. Plus, you can adjust the emissivity to get the right reading for all sorts of different surface materials - and that's a big deal when you're working with shiny metal, painted pipework, or some other non-standard
