Question
Will scratches on the vial left by the TU5300 sc/TU5400 sc Automatic Cleaning Module (ACM) influence turbidity readings?
Summary
TU5300 sc/TU5400 (TU5) sc ACM maintenance information.
Answer
Use the following guidelines for whether or not scratches will affect measurements on a TU5 process turbidimeter:
-If the bottom of the vial is dirty/scratched but the vial side walls are clean, there is negligible to no influence on measurement
-If the bottom of the vial is clean but the vial side walls are dirty/scratched, there is negligible to no influence on measurement
-If both the vial bottom and vial walls are affected by dirt and scratches, turbidity will begin to rise
