Building superb quality high-end meters involves not only good product design but also the use of high quality components as well as industrial level manufacturing process. Besides using close-case calibration design principles, Brymen products use excellent electro-plated PCBs and components for superb reliability as that can easily affect the ultimate functioning of the meter. Brymen also puts a lot of efforts in soldering workmanship as well as PCA cleanliness. Getting rid of hard-to-notice cold-soldering as well as achieving long-term high-impedance PCA conditions are the keys to long-term product reliability.
