ACL's cylindrical powder-coated 5-lb resistance probes are used with resistance meters like the ACL 395 and megohmmeters like the ACL 800 for conducting point-to-point (RTT) and resistance-to-ground (RTG) tests. Built in the USA according to criteria outlined in ANSI/ESD standards such as STM4.1, and STM7.1 and TR53. The conductive contact rubber pads allow the resistance between the two weights to be less than 1.0 x 10e3 ohms when measured on a metallic surface.
