Overview Like the PSK-310, the PSK-312 Kit is the choice of advanced professionals and the ultimate in advanced auditing and material testing. The PSK-312 includes all of the equipment in the PAK-210 Kit and adds the Prostat PRF-911 Concentric Ring Fixture and the PTB-920 Dual Test Bed for surface and volume resistivity measurements of packaging and other flat materials. The unique PRF-911 Concentric Ring Fixture is used with the PRS-812 Resistance Meter for reliable measurement of packaging material resistance and resistivity. It is used with the PTB-920 Dual Sided Test Bed to make resistance measurements recommended by EIA-541 (ASTM D 257) and ANSI/ESD S11.11-1993 guidelines for surface resistance and volume resistivity measurements. Because of its spring loaded center electrode, the PRF-911 Concentric Ring Fixture maintains even contact with materials under test and minimizes the need for frequent recalibration. The PSK-312 also incorporates the PRS-812 Resistance Meter Set, making the kit one of a highly advanced static control measurement and auditing system. Also included is the PHT-771 for temperature and humidity readings, modified wrist straps for instrument and personnel grounding, a common point ground adapter plug, clamps, clips and an operator's manual. It is all contained in a molded carrying case with retractable handle and wheels. The PSK-312 is easily customized to meet the most demanding auditing or process evaluation requirements.
