Why Buy Thunder!

Because this Thunder Scientific Model 2500 which was manufactured in August of 1992 (s/n 9208014) is still in service today; 29 years after it rolled off the assembly line. For a customer to get nearly 30 years of use out of any instrument is almost unheard of in the throwaway culture of today. So, when purchasing a Thunder Scientific generator, our customers are secure in the knowledge that we stake our reputation on our products of which, continual product support is an integral component. Thunder has been in business since 1966 and with equipment items still working flawlessly after all that time, it is proof that Thunder has and will continue in the pursuit of making quality equipment which stands the test of time. What makes Thunder’s generators better than those of our competition, the fact that our equipment is built to last. 30 years of use… that timeframe is longer than most of our competitors have even been in business.
