INFRATEK 107A SINGLE- AND THREE PHASE POWER ANALYZERS
HIGH SPEED
The MODEL 107A HIGH SPEED POWER ANALYZER is a very advanced measurement tool designed to
offer the scientist, engineer, or technician more electrical and mechanical signal information than is normally
found in one single instrument.

HIGH PERFORMANCE, EASY TO USE
The Infratek Model 107A Power Analyzers are multipurpose
instruments designed for laboratory and field use, for production
testing and quality control. High accuracy, wide frequency range, and
high common mode rejection are prerequisites for precision
measurements on inverters, light ballasts, and ultrasonic transducers.
The 107A measurement capabilities and simplicity of use are
unmatched.
