A WELL Compliance kit for consultants and air quality professionals. Features the proven Series 500 portable monitor, PM (PM2.5/PM10) , ozone and carbon monoxide sensor heads.

Indoor portable monitor starter kit

Indoor Air Quality Test Kit (Starter)

An indoor air quality testing kit for users who want an affordable set of tools to measure common indoor pollutants. Includes the Series 500 portable monitor, PM (PM2.5/PM10), COand VOC sensor heads.


Sensors are housed within an interchangeable ‘sensor head’ that attaches to the monitor base. Each sensor head contains a single gas or particle sensor. Swapping sensor heads takes seconds, can be done in the field, and no configuration or re-calibration is required.

Active sampling is a key design feature. Each sensor head contains a fan that works continuously or periodically (depending on the sensor type) to draw sample air to the sensor. Once sampled the air is exhausted from the opposite side of the sensor head.

The monitor base itself is a flexible electronic platform designed to fit comfortably in the hand. The monitor base comes in different models with different features.

The full-featured Series 500 has on board data-logging, has digital and analog outputs, and comes bundled with free desktop software. It can also be zero and span calibrated in the field allowing for maximum traceability.

Aeroqual portable air quality sensor: how it works


Aeroqual portable monitors can be configured with 28 different gas and particle sensors. Some sensors used in the portable monitor range are made by Aeroqual, others we source from best-of-breed manufacturers. In any case, each sensor is subjected to rigorous testing and quality control, and is given a multi-point span and zero calibration before being shipped.

Here is a list of gaseous and particulate pollutants that can be measured using the an Aeroqual portable monitor. Note some sensors come in different ranges, so you can choose the one that fits your application best.

  • Ammonia
  • Carbon Dioxide
  • Carbon Monoxide

  • Formaldehyde
  • Hydrogen
  • Hydrogen Sulfide
  • Methane
  • Nitrogen Dioxide
  • Ozone
  • Particles 2.5 microns and less
  • Particles 10 microns and less
  • Perclorethylene
  • Sulfur dioxide
  • VOC

Step 2 – Download data

Using the Series 500 model, connect to a PC and download your measurements using Aeroqual’s free software. Data can be exported from there to Excel. The Series 300 and 500 models can also output data directly via 0-5V and RS232.

Aeroqual portable indoor air quality monitor analyze data

Step 3 – Analyze data

Analyze your data to identify trends, discover leaks or pollution hotspots, or dive deep into the numbers for research. Data can be tagged to a location, and data is tied to the individual monitor ID. This makes large studies, involving multiple monitors and locations, easy to manage.
