vbBalancerThe dual-channel Commtest vbBalancer unbalance correction instrument is lightweight, making this instrument easy to carry on site to any problem machine. Unbalance causes high levels of mechanical stress and vibration. This is transferred directly to the bearings, resulting in a proportional reduction in normal bearing life.
With a few basic parameters, the vbBalancer calculates acceptable unbalance levels to ensure machinery operates within international ISO 1940 guidelines. The 10 hour battery life and 1 GB internal memory ensure progress is uninterrupted, practically eliminating the need to pause in order to connect to a PC or power supply. The vbBalancer also carries the legendary 5 year Commtest warranty as well as free lifetime support.


vbBalancer instrument setup is minimal, quick, and easy. Only a few calibration runs are required, with or without removing your trial weight.


The vbBalancer stores your previous balance run data, ensuring there is no need to waste valuable time performing calibration runs on repetitive or routine balance jobs.


Unbalance is computed quickly. The large backlit LCD display and user-friendly graphical interface indicate the angular position for weight correction.
