Shore Meter for Fruit Hardness Testing  

53210 Fruit Hardness Tester (non-destructive)

The Shore hardness tester is used for the hardness determination of fruit and vegetables. Hardness tests can be done in either a vertical or horizontal position and on places which are difficult to reach.

53215 Digital Fruit Shore Meter (Fruit Firmness Tester)

Technical Data:
Range 0-100 shore
Digital index
Plunger 0,25 cm2

Vegetable hardness is a very important index in the quality control process. The main advantage of this instrument is that it is non-destructive. This means it has these advantages:

  • The maturation level of fruit can be monitored throughout the plant's entire growth cycle;
  • Measurements can be carried out on the products where the classic fruit pressure tester (a destructive instrument) do not give acceptable results.

The instrument is very simple to use: once taken the instrument, place the plunger against the fruit and progressively press until the fruit is completely against the grey basement of the plunger.

For a more meaningful control it is necessary to take various samples of fruit. Two measurements must be carried out on each piece of fruit - on the opposite side of the fruit.

The determined value, average of the two measurements, is expressed in Shore degrees, range of reference for the hardness of a material.
