NAME OF THE INSTRUMENT
Infrared camera: FLIR, model B425
GENERAL DESCRIPTION
The passive IR thermography is performed using a FLIR B425, for the following purposes:
• Detection of defects / structural anomalies in architectural structures
• Thermal maps related to the presence of humidity (capillary rise and infiltration of various nature)
• Detection of detachment of plaster, or defects of architectural walls
The integration of the IR Thermography maps with measurements of the moisture content allows to obtain a “real” map of the surface distribution of humidity.
TECHNICAL DESCRIPTION
The infrared camera model B425 (FLIR) has an IR image resolution of 320 × 240 pixels resolution and an accuracy of +/- 0.5 ° C. It allows you to create thermal maps once the temperature and relative humidity of the environment, the distance from the shooting surface and the emissivity of the surface are known.
The IR images can be analyzed and processed using ThermaCAM QuickReport 1.1 software.

NAME OF THE INSTRUMENT
Thermal imager TESTO 890
GENERAL DESCRIPTION
Thanks to its extremely handling (253 x 132 x 111 mm and weighs <2Kg), the TESTO thermal imager tool available in MOLAB can be used for in situ surveys.
The camera can convert infrared (not visible) into a visible image showing the temperature distribution on the surface of the measured object without direct contact with the object to be analyzed.
Depending on the temperature, a different color is assigned, and the resulting matrix is sent to the memory and to the display of the camera as an image of the temperature (thermal) of the object.
In the field of Cultural Heritage, it is possible to acquire good quality thermograms even at considerable distances, or when a very high thermal resolution of the pixels is needed to detect cracked paintings or wall textures.
With each thermal image, a real, well-lit image can also be captured.
The camera can be used in conjunction with the DHSPI holographic system.
TECHNICAL DESCRIPTION
