Applications:
The measurement of surface and/or volume resistance
is a key parameter in describing the electrical
properties of material. In electrostatic applications the
Model 833
resistance is specified to predict the static dissipation
characteristics of material or product. Standard ESDA,
ASTM, IEC, etc probes or test fixtures may not be suitable for performing these
measurements.
ETS Custom Resistance/Resistivity Probes enable special resistance measurements to be
made on such products as gloves and finger cots, CD discs, concave/convex objects, multilayer and non-planar materials. Probes can be either modifications of existing units such as the
Model 823 (adapted from the Model 803B to measure non-planar surfaces), least conductive
buried layer of multilayer material or new special designs such as the Model 835 ESDA
STM15.1 Constant Area Force Electrode for measuring in-use resistance of gloves and finger
cots. A press is available to control the force applied to the test sample.
Description:
Custom Resistance/Resistivity Probes and test fixtures are generally designed for specific
applications such as the measurement of gloves and finger cots or the measurement of
concave and convex surfaces found in optical lenses where scratches cannot be tolerated. To
adapt to these special applications electrodes can
be designed to conform to non-planar surfaces
incorporating spring-loaded pins such as the Model
823, or independently adjusting inner and outer
electrodes utilizing conductive rubber as used with
the Model 834.
The optional Model 847 press interfaces with
virtually any probe to control the applied force. The
Model 823-847 Resistance Measurement System
with pointed electrodes can measure the resistance
of the outer layer and with additional force measure
the least conductive layer of multilayer material.
Model 834
The Model 833 Test Fixture shown on the front page is specifically
designed to measure the surface resistance of compact discs that
incorporate a center hole. It automatically aligns the electrodes
and connects the test bed to ground for making surface resistively
measurements in accordance with ASTM D 257. The electrode
dimensions are chosen to provide a fixed multiplier to the
measured resistance in order to obtain surface resistively when
applicable. The multiplication factor for the Model 833 is x100.
However, depending on the material to be measured and physical
constraints, multiplication factors of x1, x10, x100 or x1000 can be
incorporated.
Model 823-847
Custom probes or test fixtures are designed to or as close as possible to the applicable
specifications. For example, the Model 835 CAFE Fixture is designed per the applicable ESDA
STM 15.1 specification. On the other hand, the Model 823 Probe with 52 spring-loaded
electrodes conforms closely to the requirements of ESDA STM 11.11 and ASTM D 257.
