Description:
These instruments are designed to measure carbon dioxide in the range from 0 to 9,999 ppm. This range with good accuracy of meter allows users to conduct the most precise quantitative measurements of carbon dioxide in the space. The build-in temperature/humidity sensor also provides the cross-references for further analysis.
Features:
1.Fast warm up time.
2.Audible warning.
3.USB power supply.
4.Backlight display function.
5.Data Memory and Recall function.
6.Continuous data logging with time/date.
7.Precise Adjustment in different barometric levels (or pressures).
8.CO2: 0 ~ 9,999 ppm range, diffusion sampling mode.
9.Data hold & Maximum / Minimum with time stamp.
10.Energy Efficiency by sampling time modulation.
11.Easy to use USB interface and user friendly software.
12.Large Dual LCD Display for CO2, %RH humidity and temperature.
