BACK IN STOCK – Digital Desktop Multimeter / Bluetooth Speaker / Clock Alarm

It’s a floor wax! It’s a dessert topping! It’s an all-in-one benchtop multimeter that’s also a Bluetooth speaker, alarm clock, and thermometer. It can run off of USB power (plug into any wall adapter for charging your phone or gadgetry) and has built-in rechargeable batteries for portable use. Perfect for use on your workbench, coffee table, or Thanksgiving centerpiece — it’s a great conversation starter!

We couldn’t resist stocking this “it’s so uncool it’s flipped around and become cool again” engineer’s toolkit. Why stop at one feature when you can keep adding more, this solidly-built desktop multimeter has everything but the kitchen sink included. Easy to use and has a big honkin’ digital display, packed with all the bonus extras you never knew you wanted until now, including a Bluetooth speaker, alarm clock, and indoor thermometer. It’s even got built-in rechargeable batteries so you can use it on the beach, at a jazz cafe, in the middle of an outdoor wedding, or when the power is out due to a zombie infestation that has destroyed most of civilization.
