-Reduces Electromagnetic Interference from Common Laboratory Items, -Build Your Own Faraday Cage, -48" x 48" (1.22 m x 1.22 m) Sheet,-Cut to Size with Scissors, This plain square weave copper mesh can be used to build a Faraday cage for electrophysiology and other sensitive application setups to minimize the influence of external interferences such as electrostatic fields and high-frequency electromagnetic waves (e.g., AM/FM radio waves, CRT oscilloscopes, and fluorescent strip lights).Constructed from Ø0.25 mm (0.01") copper wire with 1.4 mm (0.06") spacing, this mesh offers excellent thermal and electrical conductivity and provides high air flow, making it ideal for use in Faraday cage construction or other RFI screening applications. It can be readily soldered, is easily bent and formed into shapes, and can be cut to the desired size with scissors.
