Poor indoor air quality is considered unhealthy because it causes tiredness, loss of ability to concentrate, and even illness (ex. Sick Building Syndrome). IAQ monitoring and survey, especially on CO2 levels and air ventilation systems has become widely applied in public areas such as offices, classrooms, factories, hospitals and hotels.
This meter measures CO2 level, Air Temperature, Dew Point (DP), Wet Bulb Temperature (WB) and Humidity (RH) and is an ideal instrument for Indoor Air Quality (IAQ) diagnosis.
Features
• Triple displays of CO2 level, temperature (°C/°F) and Humidity
• Stable NDIR sensor for CO2 detection
• Statistics of weighted averages
• TWA (8 hours weighted average)
• STEL (15 minutes weighted average)
• Backlight, Hold data, Min/Max
• Sound warning alarm for high-risk CO2 levels
• Easy manual calibration on CO2 and humidity
• PC connection for on-line logging and data analysis (not included in set)
• Portable Design
• Manual calibration of CO2 and Humidity is available
• Updates reading every second
• Auto / Manual power off
• Factory calibrated
