Revolv Stylus Gauge

Revolv is a small digital scale that measures the tracking force of your stylus with 0.01-gram accuracy with a capacity of 5 grams. It's small enough to fit almost anywhere, so that you can always keep it close at hand. And the easy-to-read backlit LED digital display ends the guesswork you get trying to read other types of tracking force gauges. Revolv is simple to use. Just rest the stylus of your cartridge on the stylus pad, and you're done. It includes 5 gram weight for accurate calibration. Revolv comes in a handy leatherette protective carrying case and has a slide-off cover to protect the scale. Batteries are included (two AG12 5V lithium batteries).
