A photo-ionization detector (PID) is a type of gas detector that uses ultraviolet light to ionize gas molecules, producing positively charged ions suitable for detection. PIDs are commonly used in industrial settings to detect volatile organic compounds (VOCs) in the air. They are portable, sensitive, and fast-responding instruments.

What was used in fire detectors before americium?
The first smoke detectors are based on optical principles - photoelectric detectors.
Do wired smoke detectors mount on electrical boxes?
Hard wired smoke detectors have to have a junction box behind them. These detectors use 120 volts as a working voltage. These types of detectors should be wired with 3 conductor #14 wire. The detector uses the black and white wires for the 120 volt source. Detectors these days have an output signal wire that can be connected to other detectors so that if one trips it will sound the alarm in other detectors that are on the same circuit. This output wire can be connected to other detectors by the third red wire in the 3 conductor cable.
Are there different types of gas detectors?
Yes, there are different types of gas detectors available, such as fixed gas detectors, portable gas detectors, and personal gas detectors. Each type serves specific purposes and is designed for different applications, such as industrial safety, environmental monitoring, or personal protection.
What brand of motion detectors have the the greatest range?
There are many levels of long range motion detectors, personal use and commercial use. Some motion detectors can detect movement up to 8-10 miles away. Some good brands for long range motion detectors are Honeywell and KNX.
Where can I properly dispose of smoke detectors at Lowe's?
You can properly dispose of smoke detectors at Lowe's by bringing them to the customer service desk for recycling.
What has the author James A R Samson written?
James A. R Samson has written: 'Absolute photoionization cross sections of atomic oxygen' -- subject(s): Photoionization of gases, Oxygen 'Dissociative and double photoionization cross sections of NO from threshold to 120 A'
Are infrared gas detectors the best way to detect gas leaks?
Yes. Infrared are currently considered to be the best option to detect gas leaks. They use the absorption of infrared radiation at certain wavelengths to detect dangerous levels of toxic and combustible gases.
What has the author Stuart Strathdee written?
Stuart Strathdee has written: 'The dissociative photoionization of molecular hydrogen'
What has the author L Torop written?
L. Torop has written: 'The Fano-Mies theory of photoionization resonances'
What are examples of motion detectors?
Motion detectors are: infrared detectors, ultrasonic, microwave, radiowave and... dogs.
Can radar detectors tell you if a cop car is near you?
Only if he has his radar gun on. Radar detectors are not cop detectors.
What was used in fire detectors before americium?
The first smoke detectors are based on optical principles - photoelectric detectors.
What is full form of QB detectors?
Quartzoid Bulb Detectors
What is the difference between laser detectors and radar detectors?
Laser detectors detect laser beams used by law enforcement to measure speed, while radar detectors detect radio waves used by police radar guns. Laser detectors are more precise but have a shorter range compared to radar detectors. It's recommended to have both types of detectors for comprehensive coverage.
Which stores sell the best white metal detectors?
There are many great stores that sell quality white metal detectors. These include Regton, OKM Metal Detectors, Kelly Co Detectors, as well as retailers on the Amazon website.
When was Kellyco Metal Detectors created?
Kellyco Metal Detectors was created in 1955.
When was Bureau of Alien Detectors created?
Bureau of Alien Detectors was created in 1996.
