The Enerac 500 can be configured to a compliance-level analyzer with addition of several key features. The Enerac 500 has the ability to produce Total NOx data for one. With both the NO and NO2 sensors Total NOxis obtained (NOx)=NO+NO2 on stationary combustion sources). The ability to also configure the 500 with High Sensativity sensors allows extreme accuracy over the sensors shorter range etc. Additionally, the 500 has the option to have the Thermoelectric Condenser (also called Peltier Cooler) option installed. This is a sample conditioning system (usually found on our competitors larger more expensive units) essential for proper NO2 and or SO2 gas detection and measurement. With the final addition of the viton hose, sample quality is maintained and compliance level data obtained. Therefore, the Enerac 500 is perfect for meeting your local, state and federal regulatory emissions compliance requirements.
