Overview
The Vaststar ONH-6000 oxygen/nitrogen/hydrogen analyzer uses a low-voltage, high-current water-cooled transformer — compact, with excellent heat dissipation and stable power output. Oxygen and hydrogen are measured by infrared (optional thermal-conductivity for hydrogen); nitrogen is measured by thermal conductivity. One run reports O, N and H simultaneously.
Key Features
- Highly integrated circuit design with automotive-grade electronic components for long service life and low failure rate.
- 24-bit ADC with 6 acquisition channels (high/low oxygen, high/low nitrogen, high/low hydrogen).
- 32-bit MCU for faster computation and higher accuracy.
- Integrated constant-temperature infrared detection cell; thermal insulation eliminates ambient temperature interference.
- Precision electronic mass flow controller on the analysis gas path.
- Full-function power control on the electrode pulse furnace with dynamic monitoring of power, voltage and current.
- Vertical touchscreen software for method setup, online diagnostics and data reporting.
