Maisutseb Digital Gas Mass Flow Meter 0-250L/m Air Flow Meter Sensor Oxygen, Nitrogen, Air Flow Tester Portable Gas Flow Meter Tester MF5712 Gas Flow

【Highly accurate measurement without compensation】 Adopting thermal mass flow measurement chip, this digital gas flow meter is able to measure gas mass flow directly without additional temperature and pressure compensation. Under standard condition, its flow range is up to 250L/min (or 15m³/h), the instantaneous flow resolution is up to 0.01 liter/min, and the cumulative flow resolution reaches 0.001m³, which ensures the accuracy and reliability of the measurement results. 【Wide range ratio, high sensitivity】 The mass air flow meter's single chip integrates multi-sensor functionality with a range ratio of 80:1 or even higher, enabling it to accurately measure gas flows from tiny to large. Its high sensitivity design allows even small starting flows to be accurately captured, meeting the needs of a wide range of application scenarios. 【Multiple power supply modes for flexibility and convenience】 The gas flow meter tester supports two power supply modes, either using a power adapter to connect to an external (5-24) VDC power source, or four AA batteries (6VDC). This design allows the flow meter to work continuously outdoors or in environments without a stable power supply, greatly enhancing the convenience and flexibility of use. 【High Stability and Repeatability to Ensure Accurate Measurement】 The flow meter's high stability and accuracy, as well as excellent repeatability throughout the entire process, ensures consistent measurements over long periods of time and multiple measurements. This stability is especially important for applications that require long-term monitoring and data analysis. 【Wide range of applications and support for a wide range of gases】 The flow meter supports the measurement of many gases with fast response speed and is applicable to many fields such as electromechanical, food, tobacco, analytical instruments, chemical, beverage, glass, scientific research, pharmaceuticals as well as agriculture, forestry and fishery. Parameter configuration by keypad and over-range alarm indication function make the operation easier and the use more at ease. Parameters
