Description
Product Overview
The ETCR3500B is a high‑precision insulation resistance meter designed for demanding industrial applications. Housed in a rugged 13.78 x 11.81 x 11.02 inch enclosure weighing 13 lb, it combines a full‑color touchscreen with advanced anti‑interference circuitry. Core functions include insulation resistance (IR), polarization index (PI), dielectric absorption ratio (DAR), step, ramp, and both AC/DC voltage testing. Customizable test voltage and duration settings let users adapt to unique site requirements, while built‑in monitors track live voltage, current, temperature, and humidity for added safety.
