GDZRS-2H Handheld Three-Phase DC Resistance Tester
Product Overview
To meet the needs of transformers, our company has recently developed a revolutionary product, the first handheld three-channel DC resistance tester in China. This instrument adopts brand-new technology and features high efficiency, small size (single-hand operation), light weight, and large output current. The entire unit is controlled by an ARM processor, automatically completing self-check, data processing, display, and other functions. It also has automatic discharge, automatic demagnetization, and charge/discharge indication functions.
This instrument has high measurement accuracy and is easy to operate. It is suitable for testing distribution transformers, instrument transformers, reactors, generators, motors, and other test objects. It can also be used for rapid measurement of switches, copper bars, contactors, relay contacts, metal wires, cable accessories, and other test objects, featuring fast speed and stable data.
Main Features
- A revolutionary product representing a major breakthrough in DC resistance testing technology, the first of its kind in China: a handheld three-channel DC resistance tester that is lightweight, powerful, and portable.
- The concept of one-time connection eliminates the need to reconnect and disconnect test leads, saving more time and reducing numerous safety hazards.
- Built-in ultra-large capacity lithium battery, capable of continuous operation for more than 10 hours under typical conditions (typical conditions refer to measured resistance less than 100mΩ, 2A current range, and fully charged battery).
- The test procedure is simple and efficient, with 5 test modes to choose from. The instrument automatically measures the resistance of the selected high-voltage or low-voltage winding, including high and low voltage three-phase winding measurement, or single winding measurement.
- Automatically selects test current, with a maximum current of 2A.
- Effective reading up to 50000 counts, display range 0-49999, more than 2.5 times that of similar products from other manufacturers (other manufacturers' products have effective readings of only 20000 counts or even 10000 counts, i.e., maximum display of 19999 or even 9999).
- Wide measurement range (0.1μΩ-20kΩ), suitable for distribution transformers, instrument transformers, reactors, generators, motors, and other test objects, as well as for rapid measurement of switches, copper bars, contactors, relay contacts, metal wires, cable accessories, and other test objects.
