Statfree? B2 Plus kit includes Statfree B2 benchmat and common point ground kit. Statfree? B2 Plus mat is a 0.060" thick, dissipative dual layer ESD worksurface mat. It is designed to provide a path to ground and eliminate static charge generation when used as a worksurface table mat, shelf liner, and cart liner. The surface resistance (1 x 106 to < 1 x 109 ohms Rtt) of the colour top layer meets ANSI/ESD S20.20 worksurface required limit and recommendation of ANSI/ESD S4.1 for contact with ESD susceptible items. The more conductive (< 1 x 106 Rtt) bottom black layer reduces the resistance to ground (Rtg) from the top of the surface to the groundable point and allows the mats to be used with continuous monitors.
