The instrument has the advantages of high accuracy, easy operation and easy carrying. It can be used together with the special test bench to improve the measurement accuracy.(Special note: the scientific use of the measurement range of 10%-100% of the full range, the measurement department recommends not to use less than 1% of the full range part.)Features:1. Three measurement modes can be switched freely (real-time, peak, first peak value).2. Standard fruit hardness unit Kgf/cm display.3. The upper and lower limits can be set to do statistical analysis, and the buzzer can be alarmed by setting the upper and lower limits beyond the limit.4. Automatic shutdown function: can set the automatic shutdown time, in the case of a long time no operation automatically shut down to achieve power-saving effect.5. Automatic backlight and buzzer alarm function.Specifications:Model: GY-M15 / GY-M30 (Optional)Range:GY-M15: 0.2~15Kgf/cm (x10^5 Pa) GY-M30: 0.4~30Kgf/cm (x10^5 Pa)Pressure Head Diameter: GY-M15: 11.1mmGY-M30: 7.9mmLoad Division Value: 0.01Kgf/cmAccuracy: 2%(10% to 100% of the full range)Insertion Depth of Indenter: 10mmPower Supply: 2 * 1.5V AAA Dry Battery(Not included)Working Temperature: 5-35Transportation Temperature: -10-60Relative Humidity: 15%~80%RHWork Environment: No focal source and corrosive media aroundMaterial: ABSItem Size: 120 * 60 * 31 mm / 4.72 * 2.36 * 1.22 inchItem Weight: 173g / 6.1ozPackage Size: 18.2 * 13.7 * 4.6 cm / 7.16 * 5.39 * 1.81inchPackage Weight: 454g / 16.01ozPackage List:1 * Fruit Hardness Tester1 * Press Foot1 * Hexagon Nut8 * Hexagon Cylindrical Screws1 * User Manual (English)
