The KG3125 Digital Insulation Resistance Tester adopts an embedded industrial single-chip real-time operating system, combining ultra-thin tension wire meter heads with graphical dot matrix LCD displays. This series of testers features:

• Multiple voltage output levels (500V, 1000V, 2500V, 5000V)
• High capacity and strong anti-interference capability
• Simultaneous pointer and digital display
• AC/DC dual-use functionality
• Simple operation
• Automatic calculation of various insulation indicators (absorption ratio, polarization index)
• Measurement results have a power failure protection feature

These characteristics make the KG3125 ideal for measuring the insulation resistance of large-capacity transformers, current transformers, generators, high-voltage motors, power capacitors, power cables, lightning arresters, and more.

Multiple Voltage Output Options:

• HD2000 (2500V/5000V)
• HD2010 (500V, 1000V, 2500V, 5000V) Measurement resistance range can reach 0～200GΩ, with automatic conversion of resistance ranges and corresponding indicators.

Dual Display Modes for Insulation Resistance Values:

• Mechanical pointer uses an ultra-thin tension wire structure for strong anti-vibration capability.
• The mechanical pointer allows easy observation of the insulation resistance range, while the dot matrix LCD screen guides user operations and provides precise measurement results.

Integrated Mechanical Pointer and LCD Screen:

• Dual-scale display with automatic range conversion.
• Colorful scales are easy to read, with LED displays showing corresponding colors.

Embedded Industrial Single-Chip Microcontroller and Real-Time Operating Software System:

• High level of automation and strong anti-interference capability.
• The instrument automatically calculates absorption ratio and polarization index without manual intervention.

User-Friendly Interface:

• All measurement results have power failure protection and can continuously store up to 20 sets of measurements.

Audible Prompt When Generating High Voltage:

An audible prompt is provided when the instrument generates high voltage.

Built-in Residual High Voltage Discharge Circuit:

Automatically discharges residual high voltage from the tested equipment after testing is complete.

AC/DC Dual Use:

Equipped with rechargeable batteries and an AC adapter for flexible power supply options.

Portable Design:

Easy to carry and operate in field conditions.

High Short-Circuit Current:

≥3mA high short-circuit current makes it ideal for measuring the insulation resistance of large transformers, current transformers, generators, high-voltage motors, power capacitors, power cables, lightning arresters, etc.
