P400 Handheld Portable Environmental Calibration Gas Mass Flow Meter Yidu Intelligent is developed based on the S100 standard gas laminar mass flow meter. Equipped with a rechargeable battery, it can be used in environments without a power source, with a battery life of 15 hours. Through the precise compensation and algorithms of the built-in pressure and temperature sensors, it demonstrates outstanding performance in low zero point, temperature, and pressure drift. Additionally, it features built-in settings for multiple gases and gas mixtures, with touch-screen operation for free switching, making it suitable for factories, laboratories, and other scenarios requiring on-the-go measurements.
