The ecom-ST is a compact stationary analyzer for autonomous and continuous monitoring of gas emissions. The analyzer can serve as rack insert, easily integrated in an existing cabinet or fitted with an optional protective housing for wall installation. The ecom-ST comes fitted with USB, Modbus TCP and RTU interfaces and an optional analog output. The analyzer performs from 22 up to 144 measurements per day. The ecom-ST fits a standard 19” rack and can be equipped with up to 6 gas sensors, including O2,CO,NO,NO2,SO2, CH4 (IR), CO2 (IR), H2, H2S and Combustible. It features an EPA recognized sample conditioning system containing a Peltier gas cooler/moisture removal system. Additional features are gas and ambient temperature measurement, stack pressure/draft measurement, large LCD screen with zoom capability, auto-draining, particulate filters, a flow meter, automatic CO over-range protection, sensor temperature monitoring and internal temperature compensation over the full operational range (20° to 105° F).  The analyzer calculates CO2, efficiency, and excess air.

How does it work?

    Each electrochemical sensor has a circuit housed within an electrolyte solution and when the target gas is introduced into the sensor, the half reactions (oxidation and reduction) at the electrodes generate a flow of current through the circuit. The voltage drop across the electrodes is measured by the analyzer and corresponds directly to the target gas concentration (i.e., the higher the concentration of gas, the more reactions that take place, the higher the current). In each of the electrochemical sensors we use, there is also a third reference electrode which maintains a baseline potential for increased accuracy.
