• Never install balances near heating sources such as radiators and hot

plates.

• Avoid incandescent lighting of the enclosure where radiant heat

produced will raise temperatures. (See Chapter 7 for adding an
accessory fluorescent light kit).

• Do not place the balance and enclosure on a bench that would receive

direct sunlight.

Humidity and Static Electricity Requirements

XPert:

Electrostatics can be troublesome in a balance enclosure. It is important to
understand and, to the extent possible, control static charges. An electrostatic
charged vessel, sample or enclosure can apply forces and lead to errors in
weighing. The repulsion or attraction can be detected with micro, semi micro
and analytical balances. Static charges can also lead to particulates being
attracted to surfaces within the balance enclosure. Containment of harmful
powders, prevention of cross-contamination and clean up is all enhanced
when static attraction of powders is minimized. The construction of the
XPert Balance Enclosure avoids the use of plastics, which are highly
insulative. The advantages to the glass and epoxy-coated metal construction
are twofold.

1. The enclosure does not contribute high electrostatic forces affecting

the precision of the balance.

2. The attraction and ultimate accumulation of powders, (hazardous or

nuisance), are minimized on the inside of the enclosure.

To correct or ensure against electrostatic issues, the following additional
measures may be prescribed to improve weighing operations.

• Maintain a humidity level between 45 and 60%. The ability to sustain

this humidity range can be challenging depending upon the regional
climate and HVAC system.

• Ionizers in various forms (guns, bars and blowers) are effective ways to

flood an area with ions and essentially “neutralize” electrostatic
electricity.
