• Handheld digital meter measures ambient level of carbon dioxide (CO2) to monitor indoor air quality and performance of heating, ventilation, and air-conditioning systems
• Displays current CO2 levels, long-term average CO2 levels measured over an 8-hour period, and short-term average CO2 levels measured over a 15-minute period
• Alarm notifies operator when CO2 levels reach or exceed a preset threshold, CO2 measurement up to 9999 ppm
• Liquid crystal display (LCD) shows ambient CO2 levels, as well as air, wet bulb, or dew point temperature and humidity
• Manual calibration helps ensure accurate humidity and CO2 readings
