Testo 845 Infrared Thermometer with Integrated Humidity Module Offers

For the first time, surface temperatures with smallest diameters can be measured accurately at short and long distances. The switchable optics for far-field and close focus measurement make this possible. Measurements in the far-field are made with an optical resolution of 75:1. Surface temperatures can thus be measured accurately even at greater distances from the object to be measured. At a distance of 1.2 metres from the object, the measurement point diameter is only 16 mm. A cross laser marks the measurement point exactly.

For measurements at a small distance from the object to be measured, the close focus optics provide a measurement point diameter of only 1 mm at a distance of 70 mm! Two laser points mark the measurement point.

Testo 845 Features

  • Switchable optics for far-field measurements (75:1) and close focus (1 mm, 70 mm distance)
  • Instrument memory for 90 measurement protocols
  • Backlit display (3-line) showing °C, %RH, °C td, min./max. values, alarm limit values and emissivity
  • Measurement data documentation on site with Testo report printer
