The Fluke 87V offers accuracy and diagnostics for maximum industrial productivity in the tool box or on the bench.
The Fluke 87V multimeter has improved measurement functions, troubleshooting features, resolution and accuracy to solve more problems on motor drives, in plant automation, power distribution, and electromechanical equipment.
With its newly incorporated selectable low pass filter, the Fluke 87V allows troubleshooters to take accurate voltage, current and frequency measurements on the output side of the drive at either the drive itself or the motor terminals.
Features for maximum productivity
Electrical safety
All inputs are protected to Category III, 1000 V and Category IV 600 V. They can withstand impulses in excess of 8,000 V and reduce risks related to surges and spikes.
