The AFM0725 is a thermal mass flow sensor that calculates the mass flow of the gas being measured by measuring the change in resistance. The sensor adopts
the self-developed MEMS mass flow chip, which has the characteristics of intuitive, accurate, stable, high and low temperature resistance, good linearity, and short response
time.
AFM0725 is suitable for mass flow monitoring of air, nitrogen, argon, carbon dioxide, helium, oxygen and other dry, clean and non-corrosive gases (except flammable
and explosive gases). It has been widely used in university scientific research, fire protection, environmental monitoring, tobacco, smart agriculture, food, medicine and other
industries.
The range, accuracy, repeatability and response time of AFM0725 have been strictly calibrated before leaving the factory.
