201-9 Generally speaking, how long does it take for the liquid level of fisher sub sieve sizer U-type pressure gauge to reach the maximum?
201-9 Generally speaking, how long does it take for the liquid level of fisher sub sieve sizer U-type pressure gauge to reach the maximum?
Generally speaking, when using the fisher method to measure, the water level of U-type pressure gauge will rise slowly until it reaches the highest point of the particle size value of the reflecting samples. the value it reaches within 5 minutes can be taken as the highest point.
