Trek 152P-2P User Manual

Model 152P-2P

Two Point Resistance Probe

! Performs

measurements on
areas too small to
measure with other
standard probes

!

! Exceptional accuracy,

stability, and
repeatability

!

! Wide measurement

range of 10 to 10

The Trek Model 152P-2P probe is used to perform

accurate two point resistance measurements

in the range of 10 to 10 ohms.

The Model 152P-2P probe is designed to perform resistance
measurements on objects too small to be measured using the
concentric ring probe specified in ANSI/ESD Association standard
STM11.11, or too small to be measured using the point-to-point
probes specified in other ANSI/ESD Association standards.

Items such as thermo-formed trays, tape and reel carriers, and
similar objects can now be accurately measured for their resistance
characteristics.

The Model 152P-2P probe housing is made from a dissipative, low­sloughing material for optimum performance in ESD areas.

Additional features include Elastomer electrodes, which provide
excellent surface contact, a compact probe design which is
lightweight and portable, and probe electrode pins which can be
removed for easy replacement.

A removable probe cap permits tests to be quickly performed using
a precise 90° angle on flat surfaces. With the probe cap removed,
the two independent probe electrodes can be placed in extremely
small or recessed spaces. Independent spring action of each
probe electrode allows measurements of uneven surfaces.

The Model 152P-2P operates with the Trek Model 152 Surface
Resistance Meter and most other brands of resistance meters with
banana plug inputs.
