Clamp meter, Fluke 381 - Fluke
Current clamps The new Fluke 381 clamp meter delivers all the features expected of a current clamp meter and allows the display to be removed for greater flexibility. Now one technician can perform tasks that previously required the participation of two. You can mount the Fluke 381 on a conductor, remove the display, move to another location to switch controls, or remove protective equipment, all the while seeing real-time readings. The new iFlex Flexible Current Probe (included) extends the measurement range to 2500 A ac and increases display flexibility, allows measurements on awkward sized conductors, and facilitates wire access....Current clamps
