Features
1. Precision Flame Control
- Integrated 50W/500W Bunsen burners (US-sourced, Ø9.5±0.3mm) with 20°/45° tilt adjustment.
- Auto-ignition, flame-height adjustment, and timed flame exposure (0.1S gas delay for full combustion).
2. Enhanced Safety & Observation
- Gas-leak detection with audible alarms and automatic gas shutoff.
- Heat-resistant viewing window + matte-black interior for optimal visibility.
- ≥0.5m³ wind-free stainless steel chamber with toxic fume extraction.
3. Smart Automation
- Burner auto-positioning under samples; returns post-test.
- Digital timers record afterflame/afterglow durations.
4. Versatile Fixture System
- Multi-directional clamps (up/down/left/right) for HB, V, VTM, 5VA/5VB tests.
- Compatible with horizontal/vertical configurations.
5. User-Centric Design
- LED control panel with one-key operation.
- Durable stainless steel construction, imported high-precision gauges.
