Zirconia Type Oxygen Analyzers (O2 Meters)
TF-30
Features
- Sensors and receiver can be installed at desired locations
- Lightweight and compact design allows easy integration into various systems
- No standard gas or reference air required (Calibration can be performed using air-point calibration)
- Supports low-concentration measurement (minimum range: 0–1,000 ppm)
Usage
- Reflow furnaces
- Ferrite firing furnaces
- Other atmosphere management and combustion control applications
