5KV High Voltage Insulation Tester

Wide Insulation Resistance Measurement Range
Supports up to 5TΩ at 5kV, covering both low and ultra-high resistance applications with dual accuracy specifications (±3% for lower range, ±15% for higher range).

Multiple Rated Voltages for Flexible Testing
Offers five selectable test voltages: 250V, 500V, 1000V, 2500V, and 5000V, suitable for low-voltage to high-voltage equipment such as motors, cables, transformers, and switchgear.

Comprehensive Diagnostic Functions
Built-in Polarization Index (PI) and Dielectric Absorption Ratio (DAR) calculations enable accurate assessment of insulation condition over time without manual computation.

High Output Short Circuit Current
Delivers ≥10mA output short circuit current, ensuring stable testing even under high capacitance loads, ideal for long cables or large rotating machinery.

Fully Automatic Shifting with Visual Indicators
Auto-ranging eliminates manual range selection, while LED indicator and progress bar provide real-time visual feedback during measurement.

Large LCD with Adjustable Backlight
Features a 124mm × 67mm 4-digit LCD with white backlight for clear readability in low-light environments.

USB Data Transfer & Storage
Equipped with a USB interface for exporting stored measurement data to a PC for documentation, analysis, and printing—ideal for reporting and compliance.

Real-Time Battery Status & Low Power Alert
Continuously displays remaining battery level and alerts when charging is required, preventing interruptions during critical testing.

Built-in Automatic Discharge Function
Automatically discharges capacitive residual voltage after testing, enhancing operator safety and protecting the device.

Ambient Temperature Measurement
Integrated temperature sensor allows users to reference environmental conditions during insulation testing, supporting more accurate diagnostics.

Robust Safety & Environmental Durability
Withstands AC 3700V/rms housing isolation, features high insulation resistance between casing components, and complies with IEC61326 (EMC) standards for electromagnetic compatibility.

Wide Operating Temperature Range
Operates reliably from -10°C to 40°C with humidity tolerance up to 80% RH, suitable for field and industrial environments.

Long Test Duration Capability
Measurement time adjustable from 1 to 30 minutes, accommodating both quick checks and long-term insulation stability evaluations.
