Product Description

HT9010 Lightning protection standard resistor

I. Product Introduction
HT9010 standard resistor consists of 9 1/2W high-precision military-grade wirewound resistor series to form a four-wire standard resistor. Direct shifting does not need to change the line. It is convenient to carry and replace the traditional BZ3 and other single resistors to carry the problem of inconvenient switching of different resistors. The highest accuracy is 0.05%. It is a standard resistor specially customized by us. Its resistance value includes 1mΩ, 10mΩ, 100mΩ, 1Ω, 10Ω, 100Ω, 1KΩ, 10KΩ, 100KΩ.Fully meet the range of 10^-3~10⁵ as stipulated in Order 31 of the Lightning Protection Device Inspection Qualification Management Measures. It is mainly used for the calibration of grounding resistance tester, equipotential tester and other instruments.
