|---|---|
Product Overview | A high-end precision instrument designed by Stanford Research Systems (SRS) for accurate gas composition analysis, suitable for critical industrial and scientific research processes. |
Measurement Principle | Sound velocity measurement; detects gas sound velocity and temperature, calculates component ratio/purity via a built-in database of over 500 pre-calibrated gases. |
Core Design Advantages | No chemical/optical sensors, filaments, reagents or calibration gases needed; long-term stability with drift ＜±5 ppm per year, ideal for long-term continuous operation. |
Measurement Modes | 1. Binary Gas: Measures 0–100% volume ratio of any two gases (±0.1% typical accuracy, up to 0.05%); 2. Gas Purity: Checks purity of single gases (Ar, N₂, He, etc.); 3. Physical: Displays sound velocity, temperature and pressure for gas property research. |
Key Specifications | Measurement rate: 4.4 Hz; Flow range: 0–5000 sccm (up to 20,000 sccm); Pressure range: Vacuum to 150 psia; Operation: Color touchscreen; Interfaces: USB/RS-232/RS-422, analog I/O (4-20mA, 0-10V); Matching software: BGAMon. |
Applications | Semiconductor/MOCVD process monitoring, industrial gas separation (PSA), welding shielding gas mixing, helium recovery, and laboratory research. |
Competitive Edge | Outperforms traditional analyzers (TCD, infrared/laser) with higher accuracy, better stability and zero maintenance, providing reliable gas analysis support. |
