Real-time analysis of industrial liquids

SPOT4Line is an advanced multi-angle LED spectrometer designed for precise analysis of industrial liquids. This innovative solution utilizes LED technology and spectral scattering of light to reveal the digital “optical fingerprint” of the liquid, enabling real-time validation of multiple parameters. With its non-intrusive installation on pipework, SPOT4Line performs measurements without any contact, sampling, or infiltration, ensuring the integrity of the solution passing through.

The SPOT4Line optical sensor provides accurate chemical and physical characterisation of the fluid being analysed, allowing for better quality control and process optimisation. By seamlessly integrating with standard industrial control systems, SPOT4Line enables fast data transfer and continuous results in real time. SPOT4Line supports various analyses including turbidity, color and chemical concentration, temperature control, absence of contaminants detection, and even UV measurements for non-visible pollution and nanoparticles.
