TEL 525 Deflection e/m Tube
The 525 Deflection e/m Tube is the same tube we have offered for more than 30 years. It is offered primarily for departments that have a pre-existing collection of tubes and bases, and would like a replacement tube. Both the 525 and the 2525 are built to the same high standards and will serve as a valuable educational tool for years to come.
