Compact CO, Temperature and Humidity Monitor — precise, durable and easy to carry Key benefits and why you need it Real-time safety monitoring: simultaneous detection of carbon monoxide concentration, temperature and relative humidity helps you identify dangerous conditions quickly and respond before problems escalate. Practical portability: compact, lightweight housing makes it easy to carry between rooms, job sites or vehicles so you can check air quality wherever needed. Reliable long-term use: anodized surface finish increases hardness and corrosion resistance for a longer service life in everyday and demanding environments. Clear, actionable data: the built-in 0.96-inch TFT digital display shows live measurements at a glance so you understand current conditions without extra tools. Main features Multifunctional measurement: one device supports concurrent, real-time monitoring of CO concentration, temperature and humidity. Precise, robust sensor: integrated sensor delivers stable performance in harsh environments, with high sensitivity, very low power consumption and fast processing for accurate detection results. Durable enclosure: compact case with anodized finishing provides an attractive, high-gloss appearance while improving wear and corrosion resistance. Readable digital display: 0.96-inch TFT screen presents real-time data clearly and in a more graphical, intuitive format. How it solves problems Early detection of CO reduces the risk of exposure by providing immediate concentration readings so you can ventilate or evacuate as needed. Combined temperature and humidity readings help diagnose comfort and HVAC issues, and inform decisions about ventilation and dehumidification. Low power consumption and a stable sensor mean dependable readings even in challenging field conditions, reducing false alarms and repeat measurements. Typical use scenarios Home safety: check kitchens, garages, basements and bedrooms for carbon monoxide buildup and monitor temperature and humidity to improve indoor comfort and prevent mold growth. Building maintenance and HVAC troubleshooting: rapidly verify air conditions in mechanical rooms, ductwork and occupied spaces to support diagnostics and system tuning.
