Zirconia Type Oxygen Analyzers (O2 Meters)
TF-IV
Features
- Designed for harsh combustion flue gas conditions, including high-temperature exhaust gas
- Direct furnace wall mounting eliminates the need for sampling piping or pretreatment equipment
- No standard gas or reference air required (Calibration can be performed using air-point calibration)
Usage
- Waste incinerators and sludge incinerators (combustion monitoring and control at outlet)
- Melting furnaces (combustion monitoring and control at outlet)
