RS PRO RS-5322 Air Quality Monitor

Introducing the RS PRO RS-5322 air quality monitor that measures airborne particulates with state-of-the-art technology. This unique device combines a particle counter, as well as the ability to measure air temperature, humidity and VOCs (volatile organic compounds), making this a real all in one meter for air quality measurement and monitoring. This air quality meter unit from RS PRO offers real-time measurement with the ability to record in pictures or videos for further investigation at a later stage if required. This is a great all in one device that can be used across a wide range of applications for fast, easy and accurate readings to ensure air quality standards are monitored and maintained.

Features and Benefits:

  • This hand-held and portable multi-use air quality meter from RS PRO combines a multitude of uses across a variety of applications, making it an extremely versatile meter
  • It can measure fine particulate matter (PM2.5) with a time-weighted average reading
  • The unit is also able to measure a mix of VOC gases (volatile organic compounds), with high sensitivity to H2 (hydrogen), C2H5OH (ethanol), C4H10 (butane), CO (carbon monoxide) and CH4 (methane)
  • This air quality meter is also able to measure and monitor temperature and humidity
  • It features a Health Index (0-9) detection and alarm, as well as a 6-colour, LED indication Air Quality Index Category
  • Offers a data hold and MAX/MIN with timestamp function, as well as a manual data memory and read function
  • There is a USB port connection for extra connectivity options
  • This unit has built-in data logging capabilities and is able to store 39 sets of data
  • The memory of the unit can be extended by inserting a 4GB micro SD card (not included)
  • A replaceable air filter can be used so that the whole unit doesnt need to be replaced


Generally, air quality monitors locate and monitor a variety of gases, dust, fumes and particles that could be dangerous and harmful to the breathable air quality for humans. They can also measure the immediate temperature and humidity of the air, which is also important to contributor to good air quality. Some meters have built-in gas detectors that locate and identify combustible and explosive gas leaks from petrol or gasoline, methane, butane, sewer gas, and other flammable gases that could cause serious harm to the surrounding environment and the people within that environment. Air quality meters work to measure and monitor the air quality to ensure that it is safe enough and acceptable enough to work or live in. Often, air quality meters can be used in environments like:

  • Oil production
  • Smelting
  • Chemical
  • Municipal
  • Sewage treatment
  • Electricity
  • Coal gas
  • Mining
  • Tunnel construction
  • Fire
  • Storage
  • Pharmaceutical
  • Offices

What is an air quality meter?

An air quality meter or particle counter is used to measure particles that have been scattered in the air, like dust, smoke and more. Particles like this can come from vehicle exhausts, power plant emissions, garbage and furnace incineration, and much more. Any particles like this can negatively affect the human body, both in the short term and long term, which means a particle counter can be used to measure and monitor such particles, even if they are smaller than 2.5μm.

How long does an air quality meter last?

An air quality meter is exposed to particulate matter every time it gets used. It is recommended, therefore, to use the meter 5 or fewer times a day to ensure that the service life of the unit is increased for as long as possible. An average of 5 years' use can be expected from this unit if it is kept clean and exposure to particulate matter is kept in line with the above suggestion.
