Handheld DC Resistance Tester

The Handheld DC Resistance Tester is a portable instrument designed for measuring the DC resistance of transformer windings, tap changers, reactors, and other inductive components. It's widely used for transformer manufacturing, commissioning, maintenance, overhaul, and preventive testing.

With up to 10A test current, 0.1μΩ resolution, automatic current selection, automatic discharge, and a built-in rechargeable battery, it provides a fast and convenient solution for both field and laboratory testing.

Up to 10A Test Current
Multiple test current levels provide flexibility for transformer windings, tap changers, reactors, and other resistance testing applications.

0.1μΩ Resolution
High-resolution measurement helps detect small resistance differences in transformer windings and electrical connections.

Automatic Current Selection
The automatic mode selects a suitable test current according to the test object, making operation faster and easier.

Built-in Lithium Battery
The rechargeable battery supports convenient field testing without continuous AC power.

Automatic Discharge & Protection
Automatic discharge after testing improves safety when measuring transformer windings and other inductive loads.

Compact & Lightweight
At approximately 4kg, the tester is easy to transport for field testing and maintenance.

Logo & Branding
Your company logo and branding can be applied to the unit, packaging, and user manual.

Appearance & Case Color
Product color and housing can be adjusted to match your brand or product line.

Functional Parameters
Test current levels, hardware, and software can be customized to your specification.

Software UI & Language
Interface language and documentation can be provided in English, Spanish, Vietnamese, and other languages on request.

MOQ & Lead Time
MOQ of 1 unit for logo/appearance customization. Lead time is standard production plus 1–2 weeks for customized units.
