Why Mechanical Endures

In high- radiation environments (nuclear reactors, space), semiconductors can suffer frem latch- up or bit- flips. A mechanical counter made of metal and plastic is imte to ionizing radiation. In explosive environments (oil rigs, grain elevators, chemical plants), a spark from an accordic device ce cão bee capitiphic. A purely mechanical counter generates no electrical energy and is inherenty spark.These applications mandate the use of comperical contrical.
