Features:
Sweden imported high-precision NDIR CO2 (carbon dioxide) sensing elements, measurement range, short reaction time.
Monitoring indoor air quality (IAQ) and HVAC system performance the best choice.
Indoor Air Quality Grading (Good, Normal, Poor)
Measuring temperature, humidity, carbon dioxide.
After the plug can be used without special adjustments.
Large screen display carbon dioxide / temperature / humidity / time / date
An alarm sounds and the alarm display, CO alarm values can be set
Users can self-correction
Automatic calculation display Max / Min
Record maximum and minimum CO2
