The GTC 400 C Professional enables area-wide thermography with high resolution. By capturing thousands of measurement points, a detailed thermal image is created that enables fast and comprehensive analysis.

The GIS 1000 C Professional is an infrared thermometer for precise temperature measurements on small surfaces. In addition to the surface temperature, environmental parameters such as humidity can also be recorded. This enables precise characterization of the measuring point.

Any object with a temperature above absolute zero (-273.15 °C) emits thermal infrared radiation. The intensity of this radiation is directly proportional to the temperature of the object. A thermal imaging camera converts this infrared radiation into a visible image, with different temperatures represented by different color intensities.

The GTC 400 C Professional offers a thermal resolution of 160x120 pixels. This means that the image field is divided into 19,200 individual measuring points, for each of which a corresponding temperature value is determined. The higher the resolution, the more detailed the resulting thermal image.

Thermal imaging cameras capture the infrared radiation emitted by objects and convert it into a visual signal. The resulting thermal image shows the distribution of surface temperatures. Different temperatures are represented by different colors, which enables quick and easy analysis of thermal bridges, overheating or other thermal phenomena.

The temperature measurement takes place within a circular measuring area that is precisely defined by two laser points. The measured value corresponds to the average of all temperature points within this area. In addition to the surface temperature, the device also provides information on the relative humidity and the ambient temperature.

The spatial resolution of a thermal imaging camera decreases with increasing distance. This means that smaller temperature differences are more difficult to distinguish at greater distances. In order to obtain optimal resolution and thus precise measurement values, a minimum distance of at least 30 cm from the measuring object should be maintained. This distance is necessary to adjust the focus of the camera and to ensure a sharp image of the heat distribution.

Thermal image recording begins automatically when the device is switched on. When the shutter button is pressed, a single image is captured and frozen on the display. The measurement can be continued at any time by pressing the shutter button again. Saved images can be called up and saved using the bottom left button, both during the ongoing measurement and in still image mode.

Simply press the red trigger to start the measurement. As soon as you release the trigger, the measurement ends. The device determines the average temperature within the circular area marked by the two laser points.

In addition to measuring heat, the device also offers the option of determining relative humidity and ambient temperature. The sensor responsible for this is located directly behind the protective cap. For a correct measurement, it is necessary to remove the protective cap before measuring.

"All captured thermal images are automatically saved in the gallery of the GTC 400 C Professional. To view the images, simply switch to gallery mode. You can easily scroll through your saved images using the arrow keys.

A thermal image shows temperature differences using different colors. The color palette used automatically adapts to the temperatures in the scene. This means that if you point the camera at a warmer area, the color scale will also change.

However, if you want to keep the color scale the same for different shots in order to be able to compare them better, you can lock the automatic adjustment using the right function button (Lock function on the display). An alternative way to prevent the color scale from changing automatically is to use the manual mode (using the Func function button in the measurement mode).
