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.
應用行業
應用于監測空氣、氮氣、氬氣、二氧化碳、氧氣等干燥潔凈無腐蝕性氣體(易燃易爆 炸氣體除外)的質量流量,可廣泛應用于高校科研、消防、環境監測、煙草、智慧農業、食品、醫藥等行業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
