Oxygen AnalyzersOxygen Analyzers for Baking Furnaces, N2 Reflow Ovens, and Dirty Gas
RF-400, LC-750H/PC-111
Model: RF-400

- New particle filter
Replaceable without removing the oxygen analyzer from the device - Special filter
- Improves oxygen sensor durability
- Wide AC range
Supports 100 V to 240 V AC power - Convenient measurement range
Measurement range of 0 to 10,000 ppm, commonly used in nitrogen reflow systems (0–1% range is also selectable) - Compact and easy to install
Shorter depth than conventional devices. Save space.
