- Tests individual tubers for dry matter
- An alternative to the potato hydrometer, avoids the need for a 45gal drum of water
- Ideal for measuring dry matter quickly, simply and accurately in the field
5 Easy Steps to Test Dry Matter in the Field
- Cut through the tuber
- Push the corer into the cut face
- Cut away the remaining flesh
- A clean core remains
- Take an accurate weight
The Easi-Read Dry Matter Kit is calibrated against a range of tubers using the ‘Single Tuber Suspension Method’. Using a simple chart, Easi-Read gives an accurate dry matter content of the sample. Using the kit demonstrates the high dry matter variability that can occur within samples. This relates to many Quality Control procedures where individual potatoes, not average bulks, are laboratory tested. The kit works by taking a core from a pre-cut flat tuber surface. This is then trimmed and weighed to 0.1g resolution on a very accurate balance. The resulting weight per ml is converted to percentage dry matter using a unique calibration chart. Results can be compared with the Potato Hydrometer bulk average method by taking up to ten readings and averaging them.
 
The kit is supplied in a sturdy carry case and contains all the necessary equipment for testing, including scales, corer, penknife, filter papers and calibration chart. The scales are high accuracy, measuring to 0.1g with +/- 0.2g accuracy. Available with standard ware and salad variety size corers
The field kit can test the dry matter in salad potato varieties. These are frequently too narrow for the kit’s standard corer and the dry matter calibrations for ware varieties don’t apply to the smaller potatoes. The solution is a much narrower corer and a special dry matter calibration that works for the salad varieties
