Product Features

1. Insulation resistance tester has a variety of voltage output options 500V, 1000V, 2500V, 5000V, measuring resistance range
    can reach 0 ~ 200GΩ, resistance range can be automatically converted, and there are corresponding instructions.

2. The insulation resistance value is displayed simultaneously in two ways. The mechanical pointer adopts ultra-thin tensile wire
    structure with strong earthquake resistance. The use of mechanical pointers can easily observe the change range of insulation
   resistance, and the use of dot matrix LCD screen can guide users to operate the instrument and accurately obtain the measurement results.

3. The mechanical watch head and LCD screen are combined into one. Dual scale display, automatic range conversion. The color
   scale is easy to read, and the LED displays the corresponding color.

4. Adopt embedded industrial singlechip and real-time operating software system. High degree of automation and strong anti-interference ability.
   The instrument can automatically calculate the absorption ratio and polarization index without manual intervention.

5. Friendly operation interface, various measurement results have anti-power-down function, and can continuously store 20 times of measurement results.

6. When the instrument generates high voltage, there is a prompt sound output.

7. Built-in residual high-voltage discharge circuit, the residual high voltage on the device under test can be automatically released after the test.

8. Both AC and DC use, with rechargeable battery and AC adapter.

9. The insulation resistance tester adopts a portable design, which is convenient for field operation.

10. High-voltage short-circuit current ≥ 3mA, is an ideal test instrument for measuring the insulation resistance of large transformers, transformers,
    generators, high-voltage motors, power capacitors, power cables, surge arresters and so on.
