Static Electricity Test
The tests were performed by monitoring the level of static electricity found on the work
surface and interior surfaces within the glove box. Static electricity levels were measured
with an AlphaLab Surface DC Voltmeter

.
A DESCO Emit Mini Zero Volt Ionizer

was installed in the glove box. The DESCO ionizer is a dual steady state DC
auto balancing bench top ionizer. The ionizer helps to neutralize static electricity on
surrounding surfaces. The time required by the ionizer to neutralize static electricity will
be the shortest when objects are within 12" to 36" directly in front of the ionizer. The time
for neutralization increases as the distance from the ionizer increases. The time required
for sufficient electrostatic decay will also vary depending upon user application, moisture
levels within the supply air and the level of cleanliness within the glove box interior.
