The ACL Staticide ACL 800 Digital Megohmmeter measures surface resistivity, resistance, temperature, and humidity. The ACL Staticide ACL 800 Digital Megohmmeter is a dependable and easy-to-use audit kit that is designed to test static dissipative surfaces for electrical resistivity and resistance according to industry standards such as ANSI/ESD test methods S4.1, S7.1, and STM11.11. Tests are easy to perform with or without the 5-lb probes. Unlike analog meters with LEDs, the digital LCD window of the ACL 800 Megohmmeter shows test results in actual values rather than the decade within which the measurement falls. Additionally, since ambient conditions can affect resistivity, the ACL 800 measures resistivity, temperature, and humidity with the push of one button, making the ACL 800 Megohmmeter the ideal megohmmeter for auditing.
