7755_CD_ADAPTOR Carbon Dioxide (CO2) RH & Temperature Real-Time Air Quality Monitor with PC Software Recording Analyzer
- Description
- Return, Refund, & Warranty Policy
- Reviews
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.
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 level and air ventilation become widely applied in public areas such as offices, classrooms, factories, hospitals, and hotels.
This continuous monitoring kit set includes a universal power adapter and Software CD & USB Cable for on-line data logging when connecting to PC. Data logged in the software can be exported in a chart or txt file for further analysis.
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 CO2 high-level risk
- Dual power source, battery, or 9V adaptor. Power from the battery is automatically cut off when the 9V adaptor is in use
- Easy manual calibration on CO2 and humidity
- Portable Design
- PC connection for online logging and data analysis
- Manual calibration of CO2 and Humidity is available
- Updates reading every second
- Auto / Manual power off
- Factory calibrated
