Description
The Zeal D4500 Potato Hydrometer offers a quick and simple way to measure potato dry matter.
Place a known weight of potatoes in the basket and lower the sample into water. The hydrometer then provides a direct dry matter reading.
The D4500 measures within a 17–25% dry matter range. This makes it suitable for a wide range of potato quality testing applications.
Regular checks help you monitor changes in crop quality. They can also support harvesting, storage and processing decisions.
The Zeal Hydrometer works without batteries or external power. Its simple design makes it a practical tool for everyday potato testing.
