Takedariken Advantest TR6840 Digital Multimeter –

At Mr. Scientific, we specialize in giving lab equipment a second life—so your research budget can breathe a little easier. From lasers to spectrometers, we source, test, and resell quality instruments from trusted labs and institutions. Our inventory rotates faster than a centrifuge, and we're always adding new gear that’s ready to get back to work. Whether you're launching a startup, scaling up, or just need a replacement that won’t break the bank, we've got your back. We might deal in used equipment, but we never cut corners. Each item is inspected, documented, and priced to move—because in our lab, the only thing we dilute is the markup. Mr. Scientific. Smart Science, Dumb Prices.
