Indoor Air Quality Monitor for Home, Office or School
- Unlimited data logging and memories: Built-in 2GB memory card is used to permanently record the measurement data.
- View Trend Chart in GZAIR dashboard: Logged data can be output to computers for storing. Or upload the data file to the GZAIR website dashboard for analyzing.
- Accurate Measurement: Using NDIR CO2 Sensor technologies to detect CO2, Temperature, and Humidity. The date and Time are displayed on the big LCD simultaneously.
- Beeper and LED alarm: User-adjustable CO2 high/low alarm limit, if the CO2 value in the room exceeds the pre-set value, the instrument will respond with visual and audible warning tones.
- Human/Plant Mode: Human mode measures the carbon dioxide level in close space and reminds you to ventilate timely to get good air quality; Plant mode detects whether the plant is growing in a good condition.
- Offer two ways to calibrate the sensor: Manual Calibration and Automatic Calibration. Follow the steps in the Operating Instruction to perform the manual calibration. And it can automatically calibrate itself every two weeks during the detection.

IAQ CO2 Detector, Dual-Channel NDIR Sensor, Tabletop Carbon Dioxide Meter with Data Export, Temperature and Humidity, 0~5000ppm Range
An Indoor Air Quality CO2 Monitor is an advanced device that can test simultaneously the real-time measurements of carbon dioxide gas and Environmental conditions ( Temperature, Humidity ) with level of accuracy of an industry standard reference instrument. It has the data logging function to show the Max/ Min values in the display for users to know a certain time's statue on these measuring values. The working mode have People and Plant mode, Different mode has the differnt alarm points.
Even if a plant has the perfect amount of light, water and nutrients, the limiting factor in the process of photosynthesis will be the amount of carbon dioxide available. So the greenhouse--grow vegetables and flowers and other plants, in order to make them grown quickly and faster, A real-time CO2 monitor with temperature and humidity reading will gurantees that your plants are actually getting the right amount of CO2.
This SA1200P air quality CO2 monitor can test the CO2 value, temperature and humidity at the same time and show them in the LCD display.
The instrument displays the real-time value of CO2 concentration in ppm, temperature and relative humidity.
The measured CO2 value in ppm (parts-per-million) will be displayed on the LCD with tee states indication: Good (0 to 800ppm), Normal (800 to 1200ppm), Poor (>1200ppm).
It has built-in storage for continuous data logging.
Powered by USB, or optional AC adapter.
