Hybrid ETI/ETP tomograph for wall moisture diagnostics

The modern hybrid ETI/EPT tomograph (electrical impedance and capacitance tomography) has been designed for non-invasive imaging of wall moisture conditions. Our device combines electrical impedance tomography (ETI) and capacitance tomography (ETP), providing comprehensive moisture diagnostics in residential and industrial buildings, as well as historical buildings.

Why choose our tomograph?

1. Non-invasiveness and protection of monuments
   
   Thanks to advanced measurement technology, the device eliminates the need to interfere with the wall structure. It is ideal for diagnosing monuments where traditional methods are not recommended.

2. Precision thanks to artificial intelligence
   
   Equipped with software based on neural networks, the tomograph uses machine learning algorithms to provide accurate and readable images of moisture distribution. The multi-branch LSTM/CNN network model ensures high reconstruction efficiency.

3. Versatile applications
   The tomograph will work well both in laboratory conditions and in the field, including in facilities with difficult access. It allows measurements from the side of one wall, which is particularly important in the diagnosis of basements or facades.

4. Advanced data analysis capabilities
   The system allows for normalization, denoising measurements and analysis of the impact of input variables on the results. Generating and processing synthetic data ensures the highest quality of image reconstruction.

5. Economical and ecological solution
   Minimizing diagnostic costs thanks to fast and effective analysis and the ability to monitor changes in humidity over time allow for better resource management.
