Far and near
March 1st 2006 The new Testo 845 infrared thermometer can be made to switch between close focus and far distant optics simply by moving a slide switch.
The instrument has 75:1 optics for measurements at distance. The thermometer marks the object to be measured with a laser cross to ensure that the actual position and diameter of the measurement point are identifiable during the measurement.
For close focus, the Testo 845 has a 2-point laser to mark the measurement point. The instrument can take accurate measurements of very small objects; at 70mm it will measure a spot of just 1mm diameter.
Other features include a measuring range from -35 to 950°C, accuracy to ±0.75°C, online measurement and documentation via USB and Testo software, simple operation and on-site printing to an optional infrared printer.
