About the Product
MB-350 Series Indoor Air Quality Monitors display ambient CO2 values, temperature, and humidity on an easy-to-read and long-lasting LCD panel.
These units feature bright color LED indicators of VOC and CO2 levels, which can be seen from as far as 7m away.
The USB port extends connectivity to your PC and on-site network, making this a favorite among public buildings, schools, hospitals, industrial environments, and residential structures.
