Features of photoionization detectors (pids)s
The PID you rent or lease from the KWIPPED network of suppliers will have intake and discharge ports, a display, and the internal features for operating the test. The PID will also have a power source, usually a battery. Some models come with the ability to connect to a computer for data storage and manipulation.
How photoionization detectors (pids)s work
To test an air or other gas sample PIDs send high-energy photons into the sample. The photons break molecules in the sample into positively charged ions; this causes an electric current in the gas, which is measured to compute the amount of organic matter in the gas sample. PIDs are usually handheld and can test continuously. The testing done by PIDs does not destroy the sample allowing for further tests after using the PID.
