Тестер съпротивление на заземяване 4-проводна система FR3010E

Тестер за съпротивление на заземяване FR3010E от Fuzrr. Предназначен за измерване на напрежение на заземяване, съпротивление (2-проводна), съпротивление (3-проводна) и съпротивление (4-проводна).

FR3010E обединява много функции за тестване на заземяване, които могат бързо и цялостно да измерват различни параметри в заземителната мрежа. Той използва техники за бързо филтриране, за да минимизира смущенията. Съхранява 500 комплекта данни едновременно.
