Introduction
ES9020 intelligent component tester, also known as SPD field tester,
used for arrester,, surge protector, varistor, cermet discharge tube, direct space detonator and other performance test instrument.
The instrument adopts the offline function of the charging function to overcome the shortcomings of inconvenient
on-site operation of traditional products to be plugged in.
It uses high-voltage short-circuit protection, automatic discharge function, and the meter is reliable, safe and durable.
At the same time with insulation resistance test function, the use of luxury large-screen display,
data storage, data review, compliance judgment, automatic shutdown, USB data upload and other function.
It is a commonly used and indispensable instrument for meteorological, electricity, post
and telecommunications, communications, electromechanical installation and maintenance,
and industrial enterprises that use electricity as industrial power or energy.
