LOW COST, EASY TO OPERATE
The Infratek Model 31 hand-held Power Analyzers are sophisticated
measuring instruments, single phase and three phase, designed for
laboratory and field use. Unlike other instruments in this price range
the Model 31 Power Analyzers are suitable for measurements on
frequency inverter drives, light ballasts, and other electronically
controlled loads. The wide frequency range, the high common mode
rejection, and the fact that you can measure currents of up to 50A
directly without having to use clamps guarantees excellent accuracy for
all types of measurements.
