​The Teledyne ML®661 THC system uses a conventional extractive system design to extract and condition hot, wet stack gas for a dry basis measurement using our sensor-e® THC analyzer, and Zirconium Oxide O2 Sensor. This syst​em can be configured specifically for 40CFR60/63 emission compliance, and process control applications. Similar to the extractive system, the Teledyne ML®661 is also engineered to provide a modular and cost effective solution for source monitoring while still allowing for client customization. An open architecture design is used for easy maintenance. Specialized equipment can be added for hazardous area classification requirements.​
