The KD305 series intelligent digital insulation resistance tester produced by our company adopts an embedded industrial microcontroller real-time operating system. The digital analog pointer and digital segment code display are well combined. This series of meters has multiple voltage output levels (500V, 1000V, 2500V, 5000V, 10000V), large capacity, strong anti-interference, synchronous display of analog pointer and digital, dual-use for AC and DC, simple operation, automatic calculation of various insulation indicators (absorption ratio, polarization index), and various measurement results with anti power loss function. It is a testing instrument used to measure the insulation resistance of large capacity transformers, cables, transformers, generators, high-voltage motors, power capacitors, power cables, lightning arresters, and other components.

There are multiple voltage output options for KD305 (500V/2500V/5000V/10000V), with a measurement resistance range of 0-200G Ω.

Two ways to synchronously display insulation resistance. The analog pointer adopts an easily observable range of insulation resistance changes, and a bar graph displays the measurement results.

Adopting embedded industrial microcontrollers and real-time operating software systems. High degree of automation and strong anti-interference ability, the instrument can automatically calculate absorption ratio and polarization index without manual intervention.

The user interface is user-friendly, and various measurement results have anti power failure functions, which can continuously store 19 measurement results.

When the instrument generates high voltage, there is a prompt sound output and corresponding display, with automatic voltage release function.

Built in residual high voltage discharge circuit, which can automatically discharge the residual high voltage on the tested equipment after testing.

Dual use AC/DC, equipped with rechargeable battery and AC adapter.

Automatic shutdown function: If not operated for 15 minutes after the measurement is completed, it will automatically shut down. After automatic shutdown, press the ON/OFF button for 1 second before turning on.

Set test time TIME function: Automatically perform measurements within 15 minutes of the specified time.

COMP measurement (comparative functional measurement): PI measurement (polarization index measurement). PI measurement can automatically measure the resistance ratio according to the setting at two points in time.

USB interface data transfer, high voltage prompt and red warning light, 18 sets of data storage functions.

The instrument adopts a portable design, and the backlight function is convenient for working in low light conditions, making it easy to operate in the field.

High voltage short-circuit current ≥ 3mA is a testing instrument used to measure the insulation resistance of large transformers, transformers, generators, high-voltage motors, power capacitors, power cables, lightning arresters, and other equipment.
