Results for tag: "Photoionization Detector"

The Photoionization Detector (PID) market is a segment of the optoelectronics industry that specializes in the production of devices used to detect and measure the concentration of volatile organic compounds (VOCs) in the air. PIDs are used in a variety of industries, including environmental monitoring, industrial hygiene, and safety. They are also used in the food and beverage industry to detect contaminants in food and beverages. PIDs are typically composed of a light source, a detector, and a filter. The light source is used to excite the molecules of the VOCs, while the detector measures the amount of light that is absorbed by the molecules. The filter is used to block out any background radiation that may interfere with the measurement. The PID market is highly competitive, with a number of companies offering a wide range of products. Some of the major players in the market include Thermo Fisher Scientific, RAE Systems, Honeywell, and Dräger. These companies offer a variety of PIDs, ranging from handheld devices to large, stationary systems. Show Less Read more
