Most “all-in-one” air quality detectors on the market claim to measure multiple pollutants, but they typically do so by relying on a single, low-cost semiconductor sensor and software algorithms—hardly a substitute for true multi-gas monitoring. As a result, their readings for PM₂.₅, formaldehyde, TVOC and CO₂ are often inconsistent and unreliable.

By contrast, our detector uses genuine Sensirion™ humidity-temperature chips from Switzerland and dedicated electrochemical, NDIR, and optical sensors for each target gas. Every element is calibrated on precision instruments imported from Japan and the U.K., ensuring direct measurement, exceptional accuracy, and long-term stability—so you can trust your real-time air-quality data.
