HP-901 includes all symbols according to DIN/ISO 1219 standards. This magnetic set provides a quick method of drawing Hydraulics and Pneumatic circuits on a magnetic white board for the step-by-step development of circuit diagrams.
The symbols are made of waterproof materials and adhere to a metal-backed board. Connections and designations are marked with the whiteboard marker. This symbol set is very useful to explain experimental Pneumatic circuits to a classroom of students.
