Your place in the market
Start with the questions that remove bad fits
Start with the pollutant or ventilation question and the sensing channels that can observe it
01
Before the shortlist
The first four answers do most of the work
A useful ranking starts only after the constraints specific to this market are clear.
- 01
Is the decision about ventilation, particles, radon, combustion, VOC trends, humidity or an institutional building condition?
- 02
Which channels are measured directly, estimated, cross-sensitive or absent?
- 03
Does the job require a local display or history when the app, account, network or cloud is unavailable?
- 04
What co-location, placement, calibration, response and maintenance plan will keep readings interpretable?
02
Market education
Read only as far as you need
The path changes with your research stage. Each guide is built around a decision that removes part of the market.

Market language
The terms a useful comparison should define
- NDIR CO2
- A nondispersive-infrared carbon-dioxide measurement method; published range and accuracy still depend on calibration, environment and unit condition
- PM2.5
- An optical estimate of airborne particle mass below a nominal size; aerosol type, humidity and correction can change agreement with a reference method
- VOC index
- A relative signal from a broadly responsive gas sensor, not a compound-specific concentration or proof of the source
- Co-location
- Running monitors together in the same well-mixed location to identify offsets, response differences and unit or placement problems
