Sensing Technology:
- MEMS Thermal-D® Technology: Direct mass flow measurement without temperature/pressure compensation, ensuring high accuracy in low-flow applications .
Design Advantages:
- Nano-Coated Sensor Surface: Resistant to oil, water, and fouling, enhancing long-term reliability .
- Wide Dynamic Range: 100:1 turndown ratio for precise measurement across varying flow rates .
Flexible Configuration:
- User-Configurable Parameters: Flow units (slpm/sccm), response time, and output scaling via front-panel buttons or digital interface .
- Multi-Gas Support: Factory-calibrated for CO₂ (B suffix); supports custom gas calibration (e.g., N₂, O₂) 18.
