YIDU Intelligent P200 Handheld Portable Environmental Calibration Mass Flow Meter is developed based on the S100 standard gas laminar mass flow meter, equipped with a rechargeable battery for use in environments without a power supply, with a battery life of 8 hours (15 hours for the new model). Through precise compensation and algorithms from 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.
