The Measuring Cup is useful when you’re trying to add small amounts of products to your hot tub. The measurement markings are engraved into the cup, so they won’t rub away with use. The Measuring Cup has markings for as little as 1oz/2tbsp, and 25ml.
Aside from measuring amounts, the Measuring Cup is also useful when you’re testing your hot tub water. The cup is deep enough that a test strip can be submerged easily. If you don’t use test strips, don’t worry! The spout is narrow enough to make pouring water into your testing vials a breeze. You can step out, scoop water up from your hot tub, and test it inside during the cold winter months.
