For applications with an increased demand for cleanliness, EVT has developed the Particle Inspector. Applications range from production in microelectronics and precision engineering to life sciences and healthcare.
As all clean room products, the inspector is ISO 14644 classified and VDI 2083 tested. With the Particle Inspector the levels of deposited dust, microscopic fibres, microbes and other contaminants can be detected.
The inspector 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.
The Particle Inspector has a resolution of 8µm/px and a reproducibility of up to 95% for 20 particles. The measurement area reaches up to 2.700mm² per witness plate, with a measurement time of up to 60 seconds.
After the capture, the images are digitised and transferred to a PC or Laptop. The data is then analysed and processed with the EyeVision software.
Per particle, the inspector captures the particle length and width, the particle type, and the particle position on witness plate. Additionally, the Particle Inspector captures actual samples of deposition particles to analyse and identify them. Measurement parameters are also Percentage Area Covered and Percentage Deposition Class.
