Testo’s 845 is an infrared thermometer with a difference – it can still carry out temperature measurements at a distance, but it features integrated switchable optics, allowing users to switch between close distance and long distance measurement modes on the fly.

This means that surface temperature can be calculated as close as ¼ of an inch from the targeted application, or alternatively users can stand further away (ideal if you’re measuring the surface temperature of something such as superheated piping which can be hazardous to humans if they get too close.

The 845 IR thermometer also includes a pinpoint laser sight, allowing users to accurately determine exactly where the measurement will be taken from. It’s able to measure temperature as either a Celsius or Fahrenheit reading (with measurement range of -30 to 1750°F or -35 to 950°C) and via the use of an optional relative humidity probe (sold separately) the device can measure humidity levels between a range of 0 to 100%RH.
