Descriptions

Kaiterra creates high-accuracy air quality monitors and data solutions for consumers, businesses, governments, and industrial use.

The Sensedge Mini provides real-time, accurate measurements of PM2.5, TVOC, and CO2 concentrations, as well as temperature and relative humidity readings. With multiple power, connectivity, and installation options, the Sensedge Mini is made to the satisfaction of building owners, facility managers, tenants, and employees.

Tested and certified by the RESET standard for accuracy, the Sensedge is fully compliant with various green building and air quality standards, including WELL v2, LEED, RESET, the Living Building Challenge, and Fitwel.

Designed to Make a Difference

• Best-in-Class Sensors & Algorithms
  The accuracy and reliability of your data is ensured by sensing components made in Switzerland, and the innovative cloud-based calibration used in our products.
• Modular Design
  Kaiterra’s signature modular design allows customizable modules to fit specific monitoring requirements and completely removes the need for the traditional costly calibration processes.
• Secure & Accessible Data
  Your data is brought to life by the Kaiterra Dashboard and Live Air app, where you can view real-time and historical data, identify air pollution trends, set up alerts, and download for further analysis.
