Description

The 2500V Insulation Resistance Tester is a heavy-duty, portable instrument designed specifically forfield service technicians, outdoor utility workers, and on-site maintenance engineers. Built with a dust-proof and moisture-proof housing, it withstands harsh outdoor conditions while delivering lab-grade insulation testing performance for motors, cables, transformers, switchgear, and solar/wind power systems.

Why This Tester is Built for the Field:

Rugged & Weather-Resistant– Dust-proof and moisture-proof construction ensures reliable operation on job sites, in substations, or along utility lines, even in dusty or humid environments.
Bright Backlit Display– Large 2000-count LCD with backlight allows clear readings in direct sunlight, dim switchgear rooms, or nighttime fieldwork.
True Portability– Weighs only 800g (including batteries) and fits easily into a tool bag, so you can carry it up utility poles, into manholes, or across construction sites without fatigue.
5 Test Voltages in One Box– Switch between 250V, 500V, 1000V, 2000V, and 2500V to match motor winding specs, cable insulation ratings, or transformer requirements without carrying multiple testers.
Wide Measurement Range– Measures insulation resistance from 0.1MΩ up to 200GΩ, covering everything from small control circuits to high-voltage feeder cables.
Built-in AC/DC Voltmeter (10V–600V)– Check line voltage before testing to verify the circuit is de-energized — a critical safety step for field work.
Auto Discharge– After each insulation test, the unit automatically discharges residual capacitance from the DUT, protecting you from unexpected electric shocks when disconnecting test leads.
Data Hold & 100-Memory Storage– Freeze readings on the display in bright or awkward positions, and store up to 100 test results for later report generation back at the office.
Long Test Leads with Large Alligator Clips– Securely connect to busbars, terminal blocks, or overhead lines — even with gloves on.

What's Included:

1x Insulation Tester Main Unit
1x Red alligator clip
1x Black alligator clip
1x Black Test Lead
2x Test Probes (rod-style)
1x Carrying Case
1x Instruction Manual
8x AA Batteries (required, not included)

Safety First:
This tester features a red LED high-voltage warning light on the panel, alerting you whenever 2500V is being output. The unit also includes output short-circuit protection and anti-voltage-counterattack protection, giving you peace of mind in unpredictable job-site conditions.

Technical Highlights:

Output Short-Circuit Current: < 1.8mA
Accuracy: ±(5%+10) for insulation resistance; ±(1%+5) for AC voltage; ±(0.8%+5) for DC voltage
Continuous Working Time: ≤ 30 minutes
Operating Temperature: 0°C–40°C, humidity ≤85%

Ideal for Outdoor & Field Applications:

Transmission line patrols · Wind turbine nacelle inspections · Solar farm combiner box testing · Substation breaker maintenance · Underground cable fault diagnosis · Marine electrical surveys · Construction site temporary power checks

Important Reminders for Field Users:

Always test for voltage firstusing the built-in AC/DC voltmeter before connecting the insulation test leads.
For high-resistance measurements, use the shielding terminal (G) to eliminate surface leakage errors — especially critical when testing cables in humid outdoor conditions.
After testing capacitive loads, wait for the auto-discharge to complete before removing test leads.
Store the unitin a dry place when not in use; avoid prolonged exposure to direct sunlight or rain.
