Question
Is System Check needed for the TU5300 and TU5400 Turbidimeters?
Summary
System Check on the TU5300 and TU5400 turbidimeters.
Answer
System Check is recommended because without system check, issues will be detected by inconsistencies in measurement and individual investigation will be required.

System Check is strongly recommended if the sample being measured by the TU5300 or TU5400 meets any of the below criteria:
 
Very cold samples while the TU5300 is in an ambient temperature environment or vice versa .
If sample has dissolved metals like iron, manganese, or bacteria which might coat the vial.
If environment has dust, sand  or corrosive aerosols, etc.
