HIOKI E.E. Corporation has developed the NOISE HILOGGER 3145-20 as a tool dedicated to the purpose of resolving serious electrical noise interference problems in their early stage. Noise sources such as devices that use inverters, electromagnetic emitters and radiated electrical noise from ever-faster computers will surely continue to proliferate. At the same time, because of the rapid growth of networks, the number of network-connected devices that generate interference in their environment because of noise ingress continues to grow.
