Firmness,or degree of softness or crispness, is used worldwide as a test of ripeness andmaturity of many fruits. The Fruit Tester can be used as either a hand-heldinstrument or mounted on a test and for more precise measurements.

• Rugged Construction: High impact plasticcase, aluminum dial, precision steel spring, brass mechanism chassis, impactresistant plastic crystal, stainless steel plunger and accessories. Parts disassemblefor easy cleaning.
  
• Specifications: Peak Firmness Holdbutton automatically freezes the highest reading until released by push buttonthat returns the pointer to zero. Dual Graduations; reads in Pound and Gram.Accuracy: 2 graduations through 2500 grams; 1 graduation over 2500 grams(all models).
  
• Spare Parts Included: 8 mm (5/16) and 11mm (7/16) stainless steel plunger tips, protection (splash) plate, fruitpeeler, manual, use recommendations, and carrying case. This tool is perfectlyfit to detect proper picking maturity and control fruit softening during coldstorage. It measures the pressure necessary to force a plunger of specifiedsize into the pulp of fruit.
  
• Preparing Samples: About ten daysbefore normal picking time, control pulp firmness, repeat control each 6-7 daysfor winter pome-fruits, each 2-3 days for summer pome-fruits, and stone fruits.Take samples from several plants and several spots of each plant as a randomsample will be more representative of the lot. A suitable sample will becomposed of 15-20 fruits; 2 measures have to be taken on each fruit at oppositesides, at the middle point of each side, after removing 1/2-3/4 diameter discof peel.

Slow penetration of the plunger isessential. Sharp movements and sudden pressure application may impair yourmeasurements. In order to avoid mistakes and to assure slow penetration of theplunger, make sure that the hand holding the fruit is firm, leaning it on thetable, and keep the arm rigid.
