Grip Dynamometer Kinvent K-Grip Hand Dynamometer K-Grip measures grip strength. The hand closes on the handle, the sensor reads the squeeze, and the K-Force app plots it as it happens and holds the highest value reached. Peak force is the headline parameter, and one squeeze produces it in a couple of seconds. A grip test is a short, intense effort, which makes it a quick and repeatable reference point to record. Repeat the squeeze on a set cadence and the app keeps every attempt, so the shape of the decline across a series is as visible as the single best number. All K-Grip accessories come in the box. Headline metric Peak force Highest value of the squeeze Weight 2.2 lbs Lightest of the four dynamometers Dimensions 11.81 x 3.74 x 7.87 Inches, as published Connection Bluetooth Phone or tablet, K-Force app Grip strength in seconds Peak force per squeeze Accessories all included 2.2 lbs How It Reads One Squeeze, One Number Grip is the easiest force in the body to capture cleanly, because the hand does all the work and the device sits still. ✊ Peak force as the primary output Maximum grip is taken from the top of the squeeze. Kinvent name the force peak as the most relevant measured parameter for this device, and the app surfaces it first. Force peak 🔄 Repetition series Set a series and every squeeze is stored against the same profile. Reading the values in order shows how much force the hand keeps hold of from the first attempt to the last. Series recorded 🎮 Grip as a game input The K-Force app can take live grip force as the control input for on-screen games, which turns a hold or a series of squeezes into something with a target on screen. Interactive mode 💼 Travels in the kit bag At 2.2 lbs and 11.81 x 3.74 x 7.87 in, it travels in a kit bag. Bluetooth pairing means the only other equipment needed is the phone already in the room. 2.2 lbs Why Clinics Use It A Reference Figure You Can Take Anywhere Used by physiotherapy and rehabilitation clinics, sports medicine departments and performance staff who want grip logged as a figure they can compare against next month. 🔥 Maximum grip from a single effort Peak 📊 Force values across a repetition series Fatigue ⏱ A test that fits into the gaps of a session Seconds 👥 Every attempt filed against a profile History 🎯 On-screen target during the hold Feedback 📦 Full accessory set in the box Complete 📶 Pairs to a phone already on the bench Bluetooth 🔗 One app across the whole sensor family K-Force Closer Look What A Grip Test Gives You Maximum Grip The Force Peak, In A Couple Of Seconds Maximum grip strength comes from the top of one squeeze. Nothing about the test depends on the tester's own strength or on how the device is braced, which is what makes grip such a repeatable figure to log across weeks. Force peak reported as maximum grip Reading appears while the hand is still closed Same handle position every time Device weighs 2.2 lbs Published size 11.81 x 3.74 x 7.87 in Peak force Real time 2.2 lbs Series And Holds Beyond The Single Best Squeeze The app supports isometric holds and repetition-based series as well as a one-off maximum. Each attempt lands in the record with its own value, and the run of values is the interesting part once a baseline exists. Isometric holds against a target on screen Repetition series with every attempt stored Grip force can drive the app's game modes Results filed against the person's profile Bluetooth to phone or tablet Isometric holds Repetitions K-Force app The Range How The Four Dynamometers Differ All four run on the K-Force app. The difference is where the force comes from and how it reaches the sensor.

Tensile force Traction K-Force app Shop the K-Pull Questions Frequently Asked Questions What exactly does K-Grip record? + Grip strength, taken from the force the hand applies to the handle. The primary parameter is the force peak, which the app reports as maximum grip for that attempt. Does Kinvent publish a measurement range for it? + Not in the material we hold. The published specification for this listing covers size and weight, so the numbers on this page stop where the published data stops. A precision claim needs a figure behind it, and this listing carries size and weight only. How long does one test take? + A maximum grip attempt is a short, intense effort, so a single reading is a matter of seconds. The value is on screen while the hand is still closed on the handle. Can it track a whole series of squeezes? + Yes. The app supports repetition-based series alongside single maximum tests, and stores each attempt separately so the run of values through the series is there to read afterwards. What are the game modes? + The K-Force app can use live grip force as the control input for on-screen games. It gives the person squeezing something to aim at, and the underlying force data is recorded the same way as any other test. What accessories come with it? + Kinvent list this as shipping with all K-Grip accessories included. Their listing does not itemise the set piece by piece, so we quote it as they publish it. How does it pair? + Over Bluetooth to the K-Force app on a phone or tablet. There is no cable and no base unit, so the working setup is the dynamometer and the screen. What are the dimensions and weight? + Published at 11.81 x 3.74 x 7.87 in and 2.2 lbs. Of the four Kinvent dynamometers it is the lightest, which is why it tends to be the one that travels. Who buys a K-Grip? + Physiotherapy and rehabilitation clinics, sports medicine departments, performance staff and research groups. It records a measurement; what that measurement means in a given case is for the professional taking it. Should I choose K-Grip or K-Push? + They answer different questions. K-Grip is dedicated to the hand and gives one clean grip figure with no setup. K-Push is a handheld unit pressed against a limb, covering close to 40 muscle groups with a published 90 kg range. Clinics testing both hand and limb strength commonly run the pair.
