How It Works
Specifications
The Zeal Manual Hydrometer is a traditional industry tool for fast intake sampling and measurement of potato dry matter and specific gravity (density). It is used extensively throughout the potato world by producers of crisps, french fries, potato wedges and canned, frozen and powdered potato products.
Key Features
- Simple and quick to use – static unit, uses a large water container (c.175 litre/45 gallon)
- Accurate – easy calibration (weight supplied); uses precisely-weighed potato sample
- 3 models – to suit dry matters from 14 to 27% (1.055 to 1.114 g/ml specific gravity)
3 Dry matter ranges available
D4500
Range 17-25% dry matter
1.065-1.110 g/ml specific gravity
D4501
Range 14-23% dry matter
1.055-1.095 g/ml specific gravity
D4502
Range 18-27% dry matter
1.070-1.114 g/ml specific gravity
Which manual hydrometer model should you buy?
The Zeal Manual Hydrometer is made with 3 different scales to allow for different ranges of dry matter being measured for different varieties of potato. Dry matter is not constant for a variety – it can change between years according to growing conditions and irrigation. Hence, it is not always possible to predict in advance the range of dry matter that will need to be measured.
The standard range of 17-25% (Model: POT/HYDROMETER) covers most situations. The other models (POT/HYDROMETERD4501 and 4502) tend to be used with specialist varieties.

The Zeal hydrometer is supplied with a calibration weight that lets the user check if it is floating at the Zero point on the scale in the stem before the potatoes are added to the basket. If it is not at Zero, the screw at the top of the tube can be turned slightly to raise or lower the scale inside the tube until the hydrometer floats at exactly Zero.
Easy calibration with the calibration weight supplied
