INTRODUCTION:
The Monroe Electronics Model 262A-1 Portable Surface Resistivity Meter combines fast
repeatable measurements of both surface resistivity and resistance to ground in one
versatile instrument.
With automatic ranging from 10
4
to 10
14
ohms per square in the surface resistivity mode,
10
4
to 10
14
ohms in the resistance mode and an accuracy of +1/2 decade, Model 262A-1
conveniently checks resistivity specifications for static control products such as antistatic
bags, static dissipative mats and conductive work surfaces and checks resistance of work
surfaces to ground.
Small size and rugged construction make this portable meter ideally suited for applications
in a manufacturing environment.
FEATURES:
* Measures both surface resistivity and resistance to ground.
* Easy to use - no adjustments required.
* Portable - powered by rechargeable battery.
* Wide range of direct readings in ohms per square for surface resistivity measurement
and in ohms for resistance to ground.
* Parallel bar sensing element.
* Conforms to widely accepted ASTM-D257 standard.
