E Instruments developed a new portable industrial combustion and emissions analyzer, the E4500-3. The product is designed for emissions monitoring, maintenance and tuning of many industrial combustion processes including boilers, burners, engines, furnaces, turbines, kilns and incinerators, E Instruments says. The analyzer includes a built-in printer and automatic data saving and internal memory. It includes sensors for O2, CO and NO/NOx. According to the company, there are also upgrades available that allow the user to test for NO2, SO2 or CxHy. The sensor also has a dilution pump for CO auto-range measurements up to 10 percent and comes with a software package that includes USB and Bluetooth hookups.
