True RMS Flex Clamp 281A/C/E

281 series can measure large currents in various harsh and hard to reach environments. They are designed with Rogowski flex coil with large loop (options)allowing measurement on odd size conductors and can test up to 3000A AC current. 281A/C are professional clamp meters, which meet IP54 and 2m drop proof requirements. Due to the ease in operation, accurate readings, stable performance and reliable quality, these flex clamps are ideal tools for electricians
