ОПИСАНИЕ
Серия UT270 может быстро и безопасно измерить систему заземления, не отключая линии заземления цепи и не требуя вспомогательных электродов. Они могут измерять сопротивление от 0,01 Ом с разрешением 0,001 Ом. UT275 также может измерять ток утечки до 30А. Двойная изоляция этих зажимов делает их долговечными инструментами для наружной работы и эффективно блокирует сигналы помех от окружающей среды.
