Shore Meter for Fruit Hardness Testing
53215 TP (Flat tip) & 53215 TR (Spherical tip) 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.
Range 0-100 shore
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.
