Teilch is a Technology company that develops intelligent air quality solutions for a wide range of controlled environments. Teilch’s goal is to help its clients achieve new levels of understanding of their working environment and meet the highest cleanliness regulations by building the most advanced monitoring and control systems.
Teilch has introduced to the market the most competitive airborne particle analyzers as well as cutting-edge hybrid sensor systems that provide meaningful insights, equipping customers with relevant data and systems not offered by traditional monitoring systems. Teilch provides solutions to the semiconductor, healthcare and aerospace industries.
Products: Teilch Particle Analyzers have proven significant advantages when compared to competitors’ solutions. Innovations in light source, flow control, analog and digital signal processing, components integration and software allow Teilch to provide a state of the art system for precision particle analysis.
By acquiring full and continuous particle size spectrum Teilch turns the concept of channels obsolete. This is achieved by utilizing a single stage of analog conditioning and digitalization, allowing classification of particles by software rather than by hardware, which improves reliability and accuracy and provides true particle size profiles.
