Indoor Air Quality Monitor, Real-time Wall Mount/Desktop Stand

Indoor air quality is the key to our health, comfort (both physical and mental), and even productivity. Under a CO2 concentration level of only 1000ppm, problems such as drowsiness and loss of attention may already emerge. It is very common for indoor areas like offices and classrooms to reach such a CO2 concentration level. Therefore, it is crucial to monitor indoor air quality continuously.

Our 7729 all-in-one indoor air quality monitor is your best choice to ensure you and your family’s health and comfort. Designed with a sophisticated NDIR sensor and user-friendly functions, the monitor offers real-time readings about indoor air conditions. The color of its light bar changes according to the CO2 concentration level: green when safe, yellow when alarming, and red when unhealthy. This way, you will know when better ventilation is needed.

Its wide application includes, but is not limited to, homes, offices, schools, fitness centers, restaurants, shopping malls, warehouses, and greenhouses.

Features

• Multifunctional: simultaneous, continuous, and real-time readings of CO2, temperature, and humidity levels. Monitor indoor air quality with only one instrument.
• Accurate, fast, and professional: adopts the non-dispersive infrared (NDIR) sensor, which uses sophisticated wave guide technology.
• Wide measurement range: up to 9999ppm for CO2 concentration, 99.9% for relative humidity, and 60°C (140°F) for ambient temperature.
• Easy to understand and intuitive: colorful large LED display with visual and audible alarms in case of high CO2 concentration levels. Audible alarm can be muted or disabled.
• Programmable light bar indicator: alarm level adjustable from 800ppm to 3000ppm, with the original alarm level set at 1000ppm by default.
• Dual calibration: supports both automatic background calibration (ABC) and manual calibration.
• Switchable temperature units between °C and °F.
• Mountable on wall.
• Adjustable brightness of the light bar indicator.
