• Measures and logs CO2, relative humidity and temperature
• ROTRONIC HYGROMER® IN-1 humidity sensor
• 40,000 data point memory for CO2, humidity and temperature values
• Maximum, minimum and average values displayed
• Adjustable audible and visual CO2 alarm
• Optional external temperature probe
• Includes software for configuration and data download
