Digital Earth Resistance Meter
Model 309
The model 309 Digital Earth Resistance Meter is a small, compact,
battery powered, professional meter. This easy-to-use meter is invaluable
to electricians and contractors who need to ensure the "ground" quality
and effectiveness of buildings, structures, equipment or electrical sys-
tems. A good earth ground is required for new buildings or structures
needing to pass required electrical codes. Older buildings can lose a
good, effective earth ground connection over time. This can happen
after a building or structure has been struck by lightning.
