Hub Service Tool™, the companion app for the HST-1 Bluetooth angle sensor. Designed to assist with epicyclic hub servicing on commercial, plant and agricultural vehicles.
Hub Service Tool™ is the companion app for the HST-1 Bluetooth angle sensor. It is designed to assist with epicyclic hub oil service procedures on commercial, plant and agricultural vehicles.
Connect your supplied HST-1 sensor to view the hub angle in real time. The app provides clear guidance as you rotate the hub towards the correct drain and fill positions.
Features
• Live Bluetooth angle readings from the HST-1 sensor
• Clear guidance towards each drain and fill position
• Visual, sound and vibration alerts when a target position is reached
• Choose from preset sounds
• Choose from various vibration patterns and intensities
• Support for different sensor mounting positions
• Simple zero calibration for accurate positioning
• Optional automatic connection to a remembered sensor
• Battery and Bluetooth connection information
• Simulation Mode for exploring the app using your phone’s internal motion sensor
Simulation Mode allows you to hold your phone vertically and tilt it to simulate sensor movement before connecting an HST-1. Readings from the dedicated HST-1 sensor are considerably smoother than readings produced by a phone’s internal accelerometer.
This app requires a compatible HST-1 sensor supplied by Hub Service Tool LTD. Other Bluetooth angle gauges and sensors are not supported.
