testo 845 with integrated humidity module

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. Far-field measurements are carried out at an optical resolution of 75:1. In this way, surface temperatures can be measured accurately even at great distances from the object to be measured. At a distance of 1.2 metres from the object to be measured, the measuring spot diameter is only 16 mm. A cross laser marks the measuring spot exactly during measurement. During measurements at a short distance from the object being measured, the close focus optics has a spot diameter of only 1 mm at a distance of 70 mm. Two laser points mark the spot exactly.

  • Switchable optics for far-field measurements (75:1) and close focus (1 mm, distance 70 mm)
  • Especially bright cross laser sighting for indicating the actual measurement point
  • Integrated humidity module for measuring indoor air humidity and for determining dewpoint distance
  • Reference accuracy ± 0.75 °C with super-fast measurement technology (scanning 100 ms)
  • Backlit display (3-line), shows °C, %RH, °C td, min./max. values, alarm limit values and degree of emission
  • Optical and audible alarm when limit values are exceeded
  • Probe socket for TC probe 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 printer
