降落数值仪
Rain at harvest can trigger sprouting, and millers need to know before blending whether a lot will bake well. This apparatus times the falling number from 60–1000 s using a 7.0 g sample and 25 mL water in a 100 °C bath held to ±0.2 °C. Models with 1 to 6 tube positions are available, depending on your daily sample load.
