Precision Auditor for ESD-Protected Areas. The handheld 395 Surface Resistivity Meter features sophisticated circuitry that produces higher accuracy than other pocket-sized meters. This allows for the same advantages as megohmeters, but at an economical price. Utilizing color-coded zones, the LED scale is easy to read and interpret. Half decade measurements give a closer indication to actual value. A specially colored “warning” stage alerts the auditor to material approaching the upper end of the dissipative scale, so that it can be designated as nearly out of speciﬁcation.
Unlike other pocket-sized meters, the 395 Surface Resistivity Meter features conductive rubber rails for the best contact possible. This yields higher accuracy when assessing packaging and assembly lines using the parallel resistivity probe method ASTM D257. When the optional 5-lb probes are used, this meter will comply with IEC 61340-4-1, ANSI/ESDA S4.1 & ANSI/ESDA S7.1 for RTG and RTT testing, making it ideal for auditing in ESD production areas and laboratories. The ﬂush façade of the 395 Surface Resistivity Meter is contemporary in design and functional in purpose. The face plate includes an integrated press button and provides protection for the LED scale. This prevents battery drain and lessens the potential for breakage. The 395 Surface Resistivity Meter meter can be used in all facets of material production including engineering, maintenance, quality control, incoming inspection, manufacturing and research departments for the testing of anti-static mats, ﬂoor ﬁnishes, paints, wrist straps, smocks, bags and containers.
