20 Kg x 0.01 Kg ( 10 g ) Precision Fruit Sclerometer FRUIT HARDNESS TESTER Model : FR-5120 Your purchase of this F R U I T H A R D N E S S TESTER marks a step forward for you into the...
1. FEATURES * The tester is used to measure the hardness of most kind fruits such as apple, pear, strawberry, grape, large/hard fruits, small/soft fruits. It is suitable for the fruit scientific research department, fruit company, fruit farm, agriculture colleges and universities to improve the fruit quality, the harvest storage, the product transportation...
2. SPECIFICATIONS Principal The hardness of Fruit can express by the unit area ( S ) could undertake the pressure of dynamometer ( N) , their specific value is just as the hardness ( P ). P = N / S P = Hardness value of fruit ( Kg/cm^2 ) N = Pressure of dynamometer ( N, Kg, LB ) S = Area of pressure ( m^2, cm^2 )

4. MEASURING PROCEDURE 4-1 Pay attentions for the measurement 1) When make the fruit hardness testing, it always use compression function, the display will show the '" - " mark automatically. Remark : The meter can use the " Tension " measurement, however for the fruit hardness measurement is not use this function typically.
3) Rotate the Sensing Head is prohibited. Some certain angles between Sensing Head & measuring object are not allowed ( ref. Fig. 3 ). Fig. 3 4-2 Normal Measurement 1) Slide the " Power Off/On/Peak Hold Switch " ( 3-8, Fig. 1 ) to the "...
* There are two kind sampling time of display, FAST and SLOW. Push the " FAST/SLOW Button " once ( 3-4, Fig. 1 ), if the upper left corner of LCD show " FAST " ( Fast Indicator, 3-3, Fig. 1 ), then the display reading is under the operation of fast sampling time.
5. BATTERY REPLACEMENT 1) When the LCD shows " Lo ", it is necessary to replace the batteries. However, in-spec. measurement may still be made for several hours after low battery indicator appears before the instrument become inaccurate. 2) Take out the battery cover ( 3-10, Fig. 1 ) away from the instrument and remove the batteries.

The 16 digit data stream will be displayed in the following format : D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 Each digit indicate the following status : End Word D1 & D8 Display reading, D1 = LSD, D8 = MSD For example : If the display reading is 1234, then D8 to D1 is : 1234...
7. MOUNTING HOLES & OPTIONAL TEST STAND Fruit hardness tester is a precise instrument, best results are obtained when the gauge is fitted to a test stand. Mounting holes ( 3-9, Fig. 1 ) are provided on the back of the gauge for easy stand mounting.
