P200 Handheld Portable Environmental Calibration Mass Flow Meter

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.
