1、Three Measurement Units -- Our portable digital force gauge offers flexibility in measurement, allowing you to switch between three units: N (Newton), Kg (Kilogram), Lb (Pound). 2、Three Measurement Modes -- Real-Time, PEAK, and First-PEAK. In PEAK mode, the instrument holds on to the maximum force displayed on the screen, providing you with crucial data points. 3、Automatic Shutdown Function -- Battery has short circuit, leakage, overload protection, the battery has a low battery indication, using 3.7V lithium battery power supply, at the same time, no operation for 10 minutes will automatically shut down. 4、Data Synchronization Function -- You can use the data cable to connect the meter and the computer for data synchronization testing, and you can also export and analyze the data in the software. 5、Widely Applications -- The handheld force gauge is widely applied in pull push load testing industry like electric, high & low voltage electric appliance, hardware, automobile parts, lighter and ignition system, light industry, mechanical, textile and insertion force or destructive experiment.
