⇒ ideal for everyone as an introduction to electronics
The SEK student experiments system by NTL:
- Topic-oriented structure and division according to physical sub-areas
- All areas of physics are covered
- Didactically and thematically sensible division of the sub-areas into several boxes
- Each part in the student box can also be ordered separately and purchased individually if required
- Student experiment instructions based on the curriculum and ideally matched to the composition of the boxes
- Clear arrangement of the box contents: only 1 material layer in all boxes, without confusing intermediate shelves
- Extremely stable storage boxes, non-slip stackable - and made from 100% recycled material
- Molded plastic box inserts do not become brittle and have a long service life
The standard scope of delivery of our SEK contains:
- Complete equipment set for a group of pupils
