MSA Altair 5x with PID (Photoionization Detectors)

PIDs are highly effective in detecting and monitoring various hazardous substances, ensuring the utmost safety for users. Among the many available detection methods, photoionization detectors stand out for their quick response, user-friendly maintenance, compact size, and ability to detect even low levels of hazardous gases, including volatile organic compounds (VOCs). PIDs work by ionizing gases when exposed to a PID lamp, causing them to lose an electron and become positively charged ions. This simplified illustration demonstrates the process of photoionization.
