| Humidity and temperature affect resistivity so they must be tested. The Ohm-Stat® RT-1000 tests
      resisitivity, humidity and temperature of all conductive, antistatic and static dissipative surfaces for electrical
      resistivity/resistance according to the
      EOS/ESD CECC, ANSI, ASTM, UL, NFPA, Military, and EIA test procedures. The RT-1000 includes:
        Two 5lb. 2.5" probes with handles Two 3" parallel surface resistivity probes Dissipative chair test probe (meets ANSI/EOS/ ESD Standard 12.1) Garment clamps (conforms to EOS/ESD 2.1 standard) Concentric ring probe available Foam lined carrying case  | Features:
        Easy to read digital display Measures resistivity/resistance to 103-1012 ohms Measures relative humidity-10% to 90% RH Measures temperature: 32°F to 100°F or 0°C to 37°C 10v/100v dual test voltage ranges Automatic zeroing and power off 120v or 220v AC and 9v DC alkaline or nickel cadmium Meets ANSI/EOS/ESD Standard 11.11 CE Approved NIST certificate included  |
