Portable carbon dioxide monitors are seeing steady demand growth, according to The Business Research Company's 2026 market report. The market was worth $1.25 billion in 2025 and is projected to hit $1.36 billion in 2026, then $1.93 billion by 2030. That works out to a CAGR of about 9.1% over the forecast period. Stricter workplace safety rules, confined space monitoring, and more attention to indoor air quality are the main drivers. The report segments the market by product type (handheld, wearable, multi-parameter), technology (NDIR and next-generation photoacoustic sensors), distribution channel, and end user. Key players include Honeywell, Thermo Fisher, Vaisala, Testo, and CO2Meter. One example cited is CO2Meter's PRO-10 portable detector, which measures CO2 up to 50,000 ppm and uses OSHA-aligned alarms for industrial and agricultural settings. Readers should treat the projections as directional. The press release does not provide unit shipment data, so revenue growth could reflect pricing, product mix, or expanded feature sets. Still, the report is a useful starting point for tracking the portable CO2 monitoring market and its role in workplace safety and building ventilation.
