 Time to Upgrade? Analytical Balances

Precision, range, and stability are main considerations.

So, you’re thinking of upgrading your analytical balance. Should you purchase the latest and greatest model or just repair your current instrument? It all depends on a variety of factors, but there are some major signs that it’s probably best to buy a new instrument.

“There are several performance related warning signs that indicate a balance may need repair or replacement,” says Tom Delano, vice president of business development at Adam Equipment (Danbury, CT). “Oftentimes replacement with a newer product is a better decision than repair.”

One sign that could mean it’s time for replacement is that the balance is unable to hold calibration, needing re-calibration after very few weighing tasks. If the displayed results drift up or down, jump for no apparent reason, or are consistently unstable, that’s another indication that it’s time to consider purchasing new equipment.
