Price Match Guarantee & Advice

Please note that there are two versions of this product available. The AT518L is the entry-level product, while the AT518 has larger measurement range and a few additional features (see tech specs section for more information on the tester's differences). You can choose which version of this tester you'd like to order by using the dropdown box above.

Designed for use on the move, Applent's AT518 range of testers are handheld, portable DC resistance meters suitable for use in a wide variety of applications ranging from testing low, medium and high resistors to testing connector contacts, wire resistance and measuring motor/transformer resistance.

With two models available in the range, there's a tester suited to your budget and needs. The AT518L is perfect for those who don't need as wide a measurement range; it can test DC resistance from 10μΩ to 200kΩ, while the AT518 can test across a wider range from 10μΩ to 20MΩ. The AT518L tests with accuracy of 0.1%, while the AT518 tests with accuracy of 0.05%.

In terms of design and appearance, both testers look almost identical. Each is equipped with a 3.5" true colour screen, are the same size and have built-in mini USB interfaces for attachment to other devices.
