Yidu SC200 Digital Display High-Precision Gas Mass Flow Controller Manufacturer provides metrology-grade accuracy (±0.5% setpoint accuracy) to customers with higher precision requirements. Through the precise compensation of built-in pressure and temperature sensors and core algorithms, it demonstrates superior performance in low zero, temperature, and pressure drift. Additionally, it features four selectable standard temperature conditions (0°C, 15°C, 20°C, 25°C) and displays five key parameters in real-time: temperature, pressure, standard flow rate, working flow rate, and cumulative flow rate.
