1. For applications with an increased demand in cleanliness, EVT has developed EyeCDetect (Contamination Detection)

2. Applications are ranging from production in microelectronics and precision engineering to life sciences and healthcare.

3. With EyeCDetect the levels of deposited dust, microscopic fibers, microbes and other contaminants can be detected.

4. EyeCDetect is a solution for measuring and collecting data about particle deposition at process-critical positions in the work environment. The deposition level and type of deposition is essential for effective surface cleanliness management.
