Resistance Tester

UNI-T's Insulation resistance testers feature a test voltage of up to 5,000 V, enabling them to accurately assess the insulation performance of various electrical equipment and effectively prevent electrical fires and electric shock incidents. They utilise advanced digital technology to ensure the accuracy and stability of measurement results, and are equipped with features such as automatic shut-off, a backlit display and multiple measurement modes.

• Powered by a built-in rechargeable battery, with automatic range switching, simple panel operation and a clear LCD display

• High output power and strong load-carrying capacity, capable of effectively meeting a wide range of measurement requirements

• The housing is made of high-strength aluminium alloy and features an internal equipotential protection ring and a fourth-order active low-pass filter, effectively shielding against external power-frequency and strong electromagnetic interference to ensure measurement accuracy

• For measurements on capacitive test specimens, the output short-circuit current exceeds 1.6 mA, enabling the test voltage to rise rapidly to the rated value

• During low-resistance measurements, a proportional method is employed; even if the voltage drops slightly, this does not affect measurement accuracy

• Wide range of test resistance values, suitable for insulation resistance measurements across different ranges

• Lightweight, making it easy to carry and use in the field
