Interlocking Doors

Use this feature to open either door

from the opposite side, or open

both doors with one hand. You

work more quickly and efﬁ ciently

when you can use both hands.

Eliminate One of the Major Frustrations in

Precision Weighing.

Static, while often overlooked, can seriously

degrade precision weighing. An electrostatically

charged object induces the opposite charge in nearby

objects. The resulting attraction causes inaccuracies

as shown below.

Error when weighing

a charged object

The object will appear

heavier. The value then

changes as static electric-

ity is dissipated into the

air or via the weighing

pan.

Error when a charged

object approaches

The apparent value will shift

in the negative direction.

Static attraction from a

charged object, like clothing

(frequent in dry winters) can

cause values to drift.

The Challenge.

Filter papers, disposable weigh boats and plastic

centrifuge containers can all become charged just

from normal handling. And charged powders can be

displaced, causing cross-contamination.

Better, Safer Measurements.

Understanding and removing static electricity is

critical to accurate weighing. The built-in ionizer

improves weighing by eliminating static. And

because we use the direct current (DC) method, the

ionizer needs no fan. So, you can neutralize static in

ﬁ ne powders without the risk of compromising your

sample.

Static control is so important we made the built-in

ionizer standard in all Ion Series balances. Simply

hold the sample in the upper neutralizing chamber

for a few seconds before weighing.
