Electronic Balance Showing Unstable Values

When an electronic balance is used for measuring weight, the measured value is sometimes unstable even when the windshields are closed to eliminate the influence of air movement.
This is because the force of static electricity works on the weighing dish due to electrostatic charge accumulated on the resin windshields or the worker.

Electronic Balance Showing Unstable Values

Conventional countermeasures

The worker should wait until the value stabilizes.

  • Loss in work efficiency (two to three minutes depending on the material)
  • Powder scatters due to static electricity.

Countermeasures with static eliminators (ionizers)

An ionizer eliminates the static electricity and reduces the cost for waiting. Scattering of powder can also be prevented.

Words from the worksite

Reduced cost of waiting time

Labor cost: $80/hour x Time for waiting 2 minutes x Number of measurements 10 times/day x 250 days = $6,700/year

In addition, the cost of disposing of expensive powder that scattered due to strong charges can also be reduced.
