fast change
Applications with strong surface
movement, e.g. caused by stir-
rer, primarily large tanks with
slow to medium filling speed.
Dead time: 6 s
Slewrate: 40 s
Dead time: 3 s
Slewrate: 25 s

Shortest reaction time:
• For test purposes
• Measurement in small tanks
at high filling speeds, if "rapid
change" setting is too slow.
