Feature:1. Largescreen LCD display, backlight function (suitable for night use), and the screen digital forward and backward reversal function.2. The accurate value of the gravity acceleration of the place of use can be input by oneself to make the test more accurate.3. Fruit hardness meter has peak hold function, automatic peak function and data output function.4. Fruit hardness tester is small in size, light in weight, and easy to carry. The ripeness of the fruit can be judged by measuring the hardness.5. With the builtin 1000mAh rechargeable nickelcyanide battery, the fruit penetrometer has longlasting battery life.Specification:Item Type: Fruit Hardness TesterMaterial: ABSModel: GY-4Power Supply: rechargeable nickel-cyanide battery pack 220V/AC (battery included)Battery Capacity: 1000mAhPurpose: Fruit hardness measurementDisplay: LCD display with backlight, screen digital forward and reverse functionData Output Function: data can be input to the computer through the data line for various analysesPeak Hold Function: keep the peak display until it is manually clearedAutomatic Peak Function: keep the display peak time adjustableProduct ModelGY-4UnitKgf/cmRange0.2~15 Kgf/cm (x 10^5/Pa)0.4~30 Kgf/cm (x 10^5/Pa)Indenter Value1: 11.1mm / 0.4in2: 7.9mm / 0.3inDivision Value0.01Kgf/cmAccuracy0.5%Depth of Indenter10mm / 0.4inCharging Time4~6 hoursBattery Continuous Use Time8~10 hoursStabilityTemperature drift:0.2uV/(0~60) Zero drift:0.1%/8h/F.SOperating Temperature5~35Relative Temperature0~60Environment Humidity15%~80%RHWorking EnvironmentNo seismic sources and corrosive media around.Package List:1 x Hardness Tester2 x Indenter1 x Computer Cable1 x Optical Disc4 x Screw10 x Spring Cushion1 x Nut1 x Manual 1 x Tool BoxNote:Do not use the instrument in a humid environment, a dusty environment, a place where oil or chemicals is used, or a place with an earthquake source around, so as not to cause damage.
