Mains Noise Eliminators

Signals recorded using biological amplifiers and other high impedance devices are often contaminated with 50 or 60 Hz mains noise, leading to corruption of the content of these electrophysiological signals and a degradation of the quality of subsequent data analysis.  Digitimer now manufactures the original single channel Humbug alongside our new multi-channel D400 Mains Noise Eliminator, available in 2,4 and 8 channel variants for effective removal of mains interference without signal distortion.
