ProSight ES3035 & ES3035E Digital Insulation Resistance Testers – PI/DAR and USB
Portable high-precision digital megohmmeters for insulation testing of motors, transformers, generators, cables and switchgear. Features selectable test voltages, automatic PI/DAR analysis, internal memory, USB connectivity and rechargeable battery operation.
The ProSight ES3035 and ES3035E Digital Insulation Resistance Testers are portable professional megohmmeters designed to assess the insulation integrity of electrical equipment and high-voltage systems.
Ideal for preventive maintenance, commissioning and fault diagnosis, the ES3035 Series supports insulation testing across motors, transformers, generators, electrical cables, switchgear and other industrial power equipment.
Multiple selectable test voltages allow technicians to test different equipment classes, while automatic Polarisation Index (PI) and Dielectric Absorption Ratio (DAR) measurements provide additional insight into insulation condition and deterioration.
Internal data storage and USB communication simplify test-record management, reporting and historical comparison. Rechargeable battery operation supports portable use in workshops, substations and industrial field environments.
