Resistivity Meter
Easy to Use:
To measure resistivity in ohms per
square, test using the built-in
electrodes. To measure resistivity, test
using the optional external 5-lb probes.
Detailed
The E-ST001 Resistivity Meter is a
lightweight tester for measuring surface
resistivity in ohms per square according
to the ESDA's parallel resistivity probe
method S11.11.
Easy to use, this meter shows values
through an LED scale that is coded
with colors to signify conductive,
dissipative, and insulative. There is
also a colored "warning" stage to
signal to the auditor that the material
is at the higher end of the dissipative
range and is close to being out of
specification. Half decades provide
greater accuracy by giving a closer
indication to the measurement value.
This meter is designed to be used in
all facets of material production in
cluding engineering, maintenance,
quality control, incoming inspection,
manufacturing, research, and sales
departments for the testing of antistatic mats, floor finishes,
paints, wrist straps, smocks, footwear, bags and containers.
The SL-030R Resistivity Meter and the ACL 381 Accessory
Kit combine to make a dependable audit kit for conductive
and dissipative surfaces. It is suitable for point-to-point (RTT)
and resistance-to-ground (RTG) tests. When the 5-lb probes
are used, this audit kit will comply with IEC 613404-1,
ANSI/ESDA S4.1 & ANSI/ESDA S7.1.
