HF Series Built-in Type The force gauge has advantages of high precision, easy operation and carry. What's more, it has kinds of testing modes, convenience for conner and it can store and input data to computer for statistical analysis as well as constitutes testers with different functions, combinating with test-beds and clamp. Users can input local acceleration of gravity value to make test more precise. ​Feature:1)6 digits large screen display,High precision and high resolution.2)Three display methods for selection N (Newton), kg (Kilogram) and lb (Pound) three measuring units for selection and conversion.3)Setting function of gravity acceleration4)Function of peak value maintaining.5)Automatic peak function.6)Max and min and comparison value can be set for statistic analysis.7)Data storage function,896 testing values can be stored.8)Data output function,The data can be input into computer through data line for various analyses.Specification:Model:HF-20/HF-30/HF-50/HF-100Capacity:HF-20, 20N / 2Kg / 4.5Lb.HF-30, 30N / 3Kg / 6.5Lb.HF-50, 50N / 5Kg / 11Lb.HF-100, 100N / 10Kg / 22Lb.Min unit:0.01N / 0.001kg / 0.001lb.Value error:0.5%.Units:N,Kg,Lb.Sampling speed:about 10Hz/s.Power Supply:110 to 220V AC Battery Charger or battery operation (Nickel battery 6V/1500mAh).Work temperature / Humidity:0C to 40C, 15 to 80%.Work environment:No vibrancy and corrosion.Note: The instrument cannot measure over the range, otherwise it will damage the instrument.
