The Beethoven ET series of electronic testers is specifically designed to safely check the correct operation of the related beethoven exploder. These testers are part of a range of products manufactured by Arbra instruments and our sales office would be delighted to help you select the most appropriate one for your application. Each ET tester is manufactured in a robust high impact ABS moulded case. It is completely water and dust proof. An unique feature of the tester is the use of sliding billet
terminals. This feature makes cable connection especially easy and prevents the cables from damage.

All electronic components are resin encapsulated to prevent damage.
