NONDISPERSIVE INFRARED (NDIR) SENSOR BENCH

---

Measurement of CO - CO₂ - Hydrocarbons by infrared technology

The new Enerac 700 IR and 3000E SEM-IR 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)
