*

The worksurface mat must have a conductive 

layer such as Dual Layer Rubber or Dissipative 

3-Layer Vinyl with conductive buried layers. Desco 

workstation monitors are not recommended for use with 

homogeneous matting.
ANSI/ESD S20.20 requires the use of a surface 

resistance meter for periodic verification of a 

worksurface's resistance-to-ground (Rtg). Constant 

monitors may not be used as a substitute for this 

requirement.
