Welcome - [High Accuracy] This compression force gauge is equipped with a high-precision strain gauge that can accurately measure compression force up to 180kg, with an accuracy of 0.1kg. [Bright Screen Display and USB Charging] The new bright screen display function of the compression force gauge allows you to clearly see the readings in a dark environment. It can be charged with a USB cable, which is more environmentally friendly. AAA batteries (not included) can also be used. [Easy to Use] The LCD screen of the compression force gauge clearly displays all measured values on the same screen. The displayed measurements include code, age, gender, compression value in pounds or kilograms, and compression mode. The maximum compression value and weak, normal, or strong force level can be saved and retrieved for comparison. [Automatic Storage] The hand dynamometer can store up to 19 definable data, and their data can be viewed at any time if needed; After the test, the grip strength meter can show how much the grip strength has increased or decreased this time. [Various Occasions] The digital hand dynamometer is compatible with sports training, sports, family, and clinical use. Grip strength testing is important in sports such as rock climbing, wrestling, and gymnastics, and is also an important indicator of overall health.
