*check for adequacy
MET-L-Chek, Standard- Chek & Nord-Test *
Used in temperature ranges from -5 ° С to + 50 ° С. In low temperatures (from -5 ° С to + 10 ° С ) it is necessary to increase time of
penetrating. One must take into account peculiar specifications according to DIN EN ISO 3452 part 2 & EN 571 part 1. For
examination in higher temperatures (from +10 С to + 175 С) „Super-Chek“ was especially developed..
