Back in the 1980's, Lehman Scientific got its start in refurbishing and selling mainly electronic test equipment. We also handled microscopes and other laboratory instruments. In the mid-1990's, laboratory instruments, and especially microscopes, displaced electronic test equipment as our mainstay. We have been quite successful in marketing our used and refurbished laboratory inventory. But every once in a while, we open an old warehouse and find electronic equipment. The waveguide adapters below are an example. We no longer have some of the signal generators and network analyzers necessary to test these components. So, they are being sold at a discount and are "subject to your test". This means you get to buy them at an attractive price, and get a chance to test them. If they don't meet specs, you can return them within 10 days for a full refund of your purchase price.
