Getting The Best Results; Taking Test Readings - palintest Photometer 7100 Manual

Getting the Best Results

Success in obtaining accurate and consistent test results will depend on the
care with which test procedures are carried out. Always follow the test
instructions carefully and observe the stated standing periods and temperature
conditions where applicable.
Wipe test tubes free from condensation before placing in the photometer. Test
tubes should always be kept in a clean condition. Wash and dry carefully after
use. Dirty tubes may be soaked in weak detergent solution if necessary.
Tubes which become stained or scratched in use should be replaced.
