Mettler Toledo Excellence XPE analytical balances for detecting electrostatic charge

There are many examples in the laboratory where electrostatic forces act on the weighing pan, the tare vessel and/or the sample being weighed. It is well known that these forces contribute to inaccurate results and cause slow stabilisation times.

Automatically detecting external effects to the weighing results due to electrostatic charges makes balance operation simpler and more dependable. The Excellence XPE analytical balances from Mettler Toledo incorporate StaticDetect technology which quickly and automatically detects electrostatic charge when a load is placed on the balance.

The StaticDetect indicator switches off when no influence from electrostatic charge is present and flashes when influence is present. A warning message on the SmartScreen of the balance shows the magnitude of the error.

The company has a number of measures available to avoid weighing errors caused by electrostatic charge. These measures include ErgoClips, which act as a Farady cage; and a compact antistatic device which ionises the air to neutralise charged ions on the sample.
