The K-Bubble connects by tube to an inflatable accessory. Squeeze or press the accessory, and the change in air pressure shows up as a force reading in the KINVENT app.
✓ Pressure range up to 0.4 bar (5.8 psi)
✓ Accuracy within 1.5%
✓ 36 g sensor
✓ Wireless range up to 50 m
✓ 12-hour battery
KINVENT App subscription required: the K-Bubble Pneumatic Dynamometer sends data to the KINVENT App over Bluetooth, and every KINVENT sensor needs an app subscription, from $350 per year (Starter). The free basic app has limited functions.
An inflated accessory takes the shape of the space, such as a ball held between the knees or a cushion behind the head, so the K-Bubble suits adductor and cervical testing.
Inflate the accessory more or less to change the resistance.
The KINVENT app shows the reading as it changes and records maximum and average force for each effort, so you can store results against a profile and compare them over time.
