PM measures the mass, or weight, of particles in the air. Small submicron particles in the 0.1-0.3 µm range have very little mass individually, so large numbers can be present without a substantial increase in the PM reading.

PC measures the number of individual particles in the air and profiles them by size, including small submicron particles in the 0.1-0.3 µm range. It reveals particle counts that PM mass measurements alone cannot show.

CO₂ commonly rises as people occupy a space. As a result, its trends help facility teams evaluate ventilation performance, occupancy patterns, and whether outdoor-air delivery is keeping pace with the way a room is used.

Total volatile organic compounds provide an overall signal for changing chemical emissions. For example, sources include cleaning products, finishes, furnishings, equipment, and personal-care products.

Carbon monoxide can be produced by incomplete combustion. Continuous visibility can support investigation of vehicle exhaust, fuel-burning equipment, infiltration, and other project-specific sources.

Ozone can enter from outdoors or be generated by certain equipment. Therefore, tracking it helps teams evaluate outdoor-air events, indoor sources, and conditions that may irritate the respiratory system.

NO₂ is associated with combustion sources such as traffic and gas-burning equipment. Monitoring can help distinguish outdoor infiltration from indoor combustion-related patterns.

SO₂ can be associated with fossil-fuel combustion and industrial sources. For these applications, a configured sensor can help specialized facilities and sensitive environments watch for changes over time.

Ammonia monitoring can support applications involving cleaning chemicals, refrigeration, agriculture, laboratories, waste handling, or other process-specific sources.

H₂S is a corrosive-gas indicator relevant to data centers, wastewater, industrial, and other sensitive applications. In addition, trends and alerts can be integrated into the facility response workflow.

Formaldehyde can be emitted by pressed-wood products, finishes, furnishings, and some processes. For projects that need a dedicated HCHO signal, optional monitoring provides that view.

Project-dependent sensor options can include methane, oxygen, hydrogen, phosphine, and ethylene oxide. ThinkLite selects the sensor package, range, and workflow for the use case.

Temperature affects comfort, productivity, equipment, and how occupants perceive air quality. Together, temperature and pollutant data make trends easier to interpret.

Relative humidity influences comfort, static, condensation, and mold-supporting conditions. Flair can pair RH with temperature, particle, and gas trends to give teams better context.

Barometric pressure adds environmental context and can support trend interpretation, specialty applications, and comparison of conditions across changing weather patterns.

Dew point is the temperature at which moisture can begin to condense. Indoor dew point is calculated from temperature and relative humidity; outdoor dew point comes from the connected weather data. Together, the two views help you understand moisture conditions when reviewing ventilation and condensation risk.

Configured indices turn multiple signals into a clearer status for the intended use case. They can support at-a-glance awareness, event review, thresholds, and follow-up—without replacing professional investigation or diagnosis.
