P400 Handheld Portable Environmental Calibration Gas Mass Flow Meter

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.
