Preparation

Calibration tank...1

Span standard solution...1 L (Pour the solution into the calibration tank)

Used fluid tank (Install it so that used fluid goes into the tank)

Note
Turbidity span calibration solution tends to settle. Shake thoroughly before using.
Prepare span calibration solution according to the measurement range (0 NTU to 2 NTU, 0
NTU to 5 NTU, or 0 NTU to 10 NTU).
