Measurement of Hydrocarbons by infrared technology

The new Enerac 700 and 3000E SEM-HC includes all the features of our most advanced emissions analyzer and in addition measures hydrocarbon concentrations using the latest state-of-the-art infrared technology.
The new hydrocarbons measurement capability replaces the previous combustibles measurement that used catalytic technology and is offered as an add-on option for customers.
The hydrocarbon measurement features:

Meets EPA's Reference Method 25B "Determination of Total Gaseous Organic Concentration Using a Nondipersive Infared Analyzer"
Measures Hydrocarbons as propane using the latest state of the art pulsed infrared LED emitter and dual lead selenide detector technology
Exceptional stability and accuracy at very low power consumption (less than 3 watts)
Less than 1 minute warm up time
