CHICAGO - UEi’s Smart Bell Combustion Meter™ measures CO2 and flue temperature and can be used to adjust combustion appliances such as small boilers, furnaces, water heaters, etc. It also calculates combustion efficiency, net temperature, and excess air.

According to the company, the meter uses electro-optical sensor (EOS) technology, which is new to portable flue gas instruments. This technology eliminates the need to replace oxygen sensors periodically, which lowers the cost of ownership for the user, while providing a more precise method of testing when compared to traditional wet-chemical kits.

The product won an AHR Expo Innovation Award in the Tools and Instruments category.
