The G-Meter + is designed for statutory annual MOT  brake performance testing of class III, IV, V, VI & VII vehicles.
The electronic deceleration sensor used in G-Meter+ gives it a number for advantages over older electronic devices and mechanical pendulums:
- It is self-aligning and will automatically sense the direction of travel. Precise alignment of the instrument with the direction is, therefore not necessary
 
- Its memory can record 3 sets of test results e.g main, secondary and parking brake tests. These are retained even if the instrument is switched off
 
- It has an internal clock to accurately record the time and date of each test
 
- It measures the peak deceleration, meant deceleration and stopping time and then calculates speed and stopping distance
 
- It determines any left-right pull sensed during the brake test
