Firmness is a key indicator of ripeness, so the instrument helps fruit research departments, fruit companies, farms and agricultural universities judge maturity and make better decisions on harvest, storage and transport.\u003c\/p\u003e\n\u003cp\u003eIt measures up to \u003cstrong\u003e20.00 kg (196.10 N \/ 44.10 lb)\u003c\/strong\u003e with a resolution of \u003cstrong\u003e0.01 kg\u003c\/strong\u003e and an accuracy of \u003cstrong\u003e±(0.5% + 2 digits)\u003c\/strong\u003e at 23 ± 5 °C. A load cell transducer and microprocessor circuit give stable readings, and the overload capacity is 30 kg.\u003c\/p\u003e\n\u003cp\u003eThe tester works in compression and tension, with a \u003cstrong\u003epeak hold\u003c\/strong\u003e function that freezes the maximum force reached as the tip penetrates the fruit. Readings appear on a large 5-digit backlit LCD that can be reversed for comfortable reading in either orientation, with selectable units of kg, N or lb and fast (0.2 s) or slow (0.6 s) update.\u003c\/p\u003e\n\u003cp\u003eFour penetrometer tips of \u003cstrong\u003e3, 5, 8 and 11 mm\u003c\/strong\u003e are supplied with a hard carrying case. Mounting holes on the back allow the gauge to be fitted to the optional FS-1001 test stand for more repeatable results, and an RS-232 output allows connection to a PC with the optional cable and software.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"content2\" class=\"tab-content\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable class=\"spec-table\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter \/ Feature\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProduct Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDigital Fruit Hardness Tester\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLutron\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFR-5120\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMeasuring Capacity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e20.00 kg \/ 44.10 lb \/ 196.10 N\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eResolution\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.01 kg \/ 0.01 lb \/ 0.05 N\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMinimum Display\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.02 kg \/ 0.07 lb \/ 0.3 N\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAccuracy\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e±(0.5% + 2 digits), within 23 ± 5 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOverload Capacity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMax. 30 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFunction\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTension \u0026amp; compression; normal force and peak hold\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eUnits\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ekg \/ N \/ lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDisplay\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5-digit LCD, 16 mm digit height, backlit, reversible\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eUpdate Time\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFast approx. 0.2 s; slow approx. 0.6 s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTransducer\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLoad cell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eData Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRS-232 serial computer interface\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePower Supply\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e6 × 1.5 V AA batteries or DC 9 V adapter (adapter not included)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePower Consumption\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eApprox.
