Detector size (in pixels)
info
  • The detector size indicates the number of temperature measurement points (pixels) with which the thermal imager is equipped. The more pixels, the more detailed and clearer the measuremente objects are presented.
160 x 120 320 x 240 640 x 480
SuperResolution technology
info
  • SuperResolution technology improves the image quality by one class, i.e. the resolution of the thermal image is four times higher.
(to 320 x 240) (to 640 x 480) (to 1280 x 960)
Thermal sensitivity (NETD)
info
  • The thermal sensitivity (NETD) displays the smallest temperature difference which can be resolved by the thermal imager. The lower this value is, the smaller the temperature differences which can be measured.
< 80 mK < 60 mK < 30 mK < 40 mK
Temperature measuring
range
info
  • The temperature measuring range of your thermal imager informs up to which temperature your thermal imager is able to record and measure the heat radiation of objects.
-20 C to +280 C -20 C to +350 C
Image refresh rate
info
  • The display refresh rate informs as to how frequently the thermal imager is refreshed per second.
9 Hz 33 Hz*
Standard lens
info
  • The standard lens (light wide-angle lens) records a large image section, and thus allows a fast overview of the temperature distribution of the measurement object.
32 x 23 30 x 23 42 x 32
Exchangeable telephoto lens
info
  • The exchangeable telephoto lens assists in the measurement of the smallest details and visualizes them even at greater distances in the thermal image.
false (9 x 7) false false 11 x 9 false 15 x 11
Focus
info
  • The focussing allows the focus of the thermal image to be adjusted exactly. This can be done manually, with motor support, or automatically.

Rotatable display
info
  • Using the rotatable display, thermography can be conducted safely from many additional positions (e.g. overhead) Undesired reflections on the display are avoided.

Rotatable handle
info
  • The rotatable handle allows secure handling of the thermal imager in difficult-to-access places (such as at floor level).

Touchscreen
info
  • In addition to joystick control, the thermal imager can be operated via the touchscreen.

High temperature
measurement
info
  • With the high temperature option, the measuring range can be flexibly extended. Thanks to a high temperature filter, the measurement of temperatures up 550 C / 1,200 C is possible.
false false (up to 550C) false (up to 1.200C) false (up to 1.200C)
Auto Hot/Cold Spot
Recognition
info
  • The coldest and the hottest spot on the measurement object are automatically indicated in the thermal image in the imager display. Critical heat conditions are identified at a glance.

Min-/Max on area calculation
info
  • The minimum and maximum temperatures of an image section are displayed directly on site. Critical heat conditions in this image section are identified at a glance.

Isotherm function
info
  • The optical colour alarm shows all image points whose temperature values are within a defined range, marked in colour in the thermal image.

Alarm value function
info
  • The optical colour alarm shows all image points whose temperature values are above or below a defined limit value, marked in colour in the thermal image.

Display of surface moisture
distribution via manual input
info
  • The value of the relative surface moisture is displayed for each measurement point. This is calculated from the externally measured ambient temperature and humidity as well as the measured surface temperature.
false true true false true false true
Humidity measurement with
radio humidity probe**
info
  • The value of the relative surface moisture is displayed for each measurement point. This is calculated from the ambient temperature and humidity automatically transferred in real time by wireless probe, as well as the measured surface temperature.

Measuring mode "Solar Energy"
info
  • In solar mode, the value of the sun irradiation can be entered into the thermal imager. This value is stored with each thermal image and is then available for analysis in the evaluation software.

Voice recording
info
  • Localized weak spots can be easily commented using voice recording. Additional information is thus documented directly on site.

Integrated digital camera
info
  • Parallel to the thermal image, a real image of each measurement object is also stored. A faster and easier object inspection can be carried out due to the simultaneous display of thermal and real images.

Integrated power LEDs
info
  • The power LEDs guarantee optimum illumination of dark areas when recording real images.

Wizard to create panoramic images
info
  • For large measurement objects, the panorama image assistant allows the analysis and documentation of a total image stitched together from many individual images. There is no need to administer, view and compare several images.

Technology SiteRecognition (+ Object recognition control of thermal images)
info
  • The SiteRecognition technology takes care of the recognition, storage and administration of the thermal images for periodic inspection tours with similar measurement objects.

Video measurements (at max. 3 points)
info
  • With the video measurement, thermographic video recordings can be directly transferred to a PC. Up to 3 measurement points are available for each individual image, and can be analyzed.

Creating a fully radiometric video, incl. function data acquisition (via USB)
info
  • With the fully radiometric video measurement thermal processes can be thermally analyzed in real time (also periodically and event based). For every instant, all temperature measurement points are exactly available per pixel.

Laser***
info
  • Using the laser pointer, a laser spot can be displayed on the measurement object, for orientation purposes. With the laser marker, this laser point is also shown parallax-free in the display of the thermal imager.
