The retz digital gas mass flowmeter is based on the principle of thermal measurement, combined with a mass flow chip. It has a compact size and a high recognition digital display screen, suitable for various scenarios that require gas flow measurement. This product calculates the mass flow rate of the measured gas by measuring resistance changes. It has the advantages of intuition, accuracy, stability, high and low temperature resistance, good linearity, fast response time, high overall integration, and high cost-effectiveness.
应用行业
应用于监测空气、氮气、氩气、二氧化碳、氧气等干燥洁净无腐蚀性气体（易燃易爆 炸气体除外）的质量流量，可广泛应用于高校科研、消防、环境监测、烟草、智慧农业、食品、医药等行业Applied to monitor the mass flow rate of dry, clean, and non corrosive gases (excluding flammable and explosive gases) such as air, nitrogen, argon, carbon dioxide, and oxygen, it can be widely used in industries such as university research, fire protection, environmental monitoring, tobacco, smart agriculture, food, and medicine
