Newtons4th Ltd (N4L)

Power Analyzer & Analysis, Frequency Response Analyzer & Analysis, Gain Phase Analyzer & Analysis, Transfer Function Analyzer & Analysis, Impedance Analyzer & Analysis, Selective Level meter,

Newtons4th Ltd (N4L) was established in 1997 to design, manufacture and support innovative electronic measurement instruments for the world-wide market. Specialising in sophisticated test equipment, particularly for phase measurement, our product portfolio includes power analyzers, frequency response analyzers (gain/phase analyzers), phase angle voltmeters (vector voltmeters), phase meters, LCR meters, transformer analyzers, true RMS voltmeters, selective level meters, power analyzers and harmonic analyzers.

The company was founded on the principle of using latest technology and sophisticated analysis techniques in order to provide our customers with accurate, easy to use instruments at a lower price than has been traditionally associated with these types of measurements.

Our name, Newtons4th

The name Newton (Sir Isaac) is synonymous with a thorough understanding of physical principles from observation of the real world. His well known 3 laws of motion are so simple and clear that they are easily learned and applied, yet they give us the tools to analyze the motion of very complex systems. The number 4 represents innovation, building on what is already established. Newtons4th - innovation based on established fundamental principles.
