SB2235 series insulation resistance meter (electric shaker)Detailed product description：

The SB2235 series insulation resistance meter adopts multiple advanced technologies and is suitable for accurate measurement of insulation resistance, absorption ratio, and polarization index of transformers, cables, motors, switchgear, and other industrial equipment in adverse environments, especially in 220000 volt substations. The enterprise standards for producing this series of instruments have been approved and filed by the national quality and technical supervision department, and the personnel responsible for formulating the standards of the company have participated in the standard formulation work of the national power industry department. There are twelve models of insulation resistance meters in this series.
