Productdescription

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.

  • Switchable optics for far-field measurements (75:1) and close focus (1 mm, 70 mm distance)
  • Especially bright cross laser sighting for indicating the actual measuring point
  • Reference accuracy ± 0.75 °C with super-fast measurement technololgy (scanning 100 ms)
  • Backlit display (3-line) showing °C, min./max. values, alarm limit values and degree of emission; additional display with humidity module: %RH, °Ctd
  • Optical and audible alarm when limit values are exceeded
  • Probe socket for TC probes for determining emissivity
  • Instrument memory for 90 measurement protocols
  • PC software for archiving and documenting measurement data (included in delivery)
  • Tripod fitting for online measurement via USB cable (included in delivery)
  • Measurement data documentation on site with Testo report printer
  • Aluminium case for instrument and accessories (included)
