Determine and monitor the correct transmission

The UV-C light must be able to penetrate the liquid well in order to reach and break down the micro-organisms everywhere. The correct transmission of a fluid, or light permeability, is therefore of great importance. The less light the liquid absorbs, the better the polluting organisms can be reached. A high transmittance means the light penetrates deep into the liquid and the further this light penetrates, the more water can be illuminated at the same time with the same power. The transmission is usually measured over a distance of 10 mm (T₁₀) or 50 mm (T₅₀) and the result is displayed in percentages, so with 90% transmission T₁₀ 90% of the light is transmitted through 1cm of liquid.

Due to our extensive knowledge of UV-C technology, we know that the right transmission is decisive for every water-related challenge. Together we achieve the most efficient disinfection systems for every water-related challenge.

The exact transmission of a liquid is impossible to determine with the naked eye, as we cannot see UV-C light. It is calculated as the fraction of the original light that passes through the liquid (I/I₀). To determine or monitor the exact transmission of a fluid, we have RealTech transmittance meters in our range. These are available in portable and online versions.
