Why Every Power Engineer Needs a Low Resistance Ohmmeter
When it comes to electrical power systems, every micro-ohm matters.
Loose connections, oxidized joints, damaged busbars, worn circuit breaker contacts, and poor cable terminations can generate excessive heat, increase energy losses, and eventually lead to costly equipment failures or unexpected outages.
The Megger DLRO100XB Digital Low Resistance Ohmmeter is designed to detect these hidden problems before they become critical.
Using a powerful 100A DC test current, the DLRO100XB accurately measures extremely low resistance values in the micro-ohm range, making it the ideal instrument for:
✅ Circuit Breaker Contact Resistance Testing
✅ Busbar Joint Verification
✅ Cable Joint & Termination Testing
✅ Switchgear Maintenance
✅ Transformer Connection Inspection
✅ Earthing & Bonding Continuity Tests
✅ Preventive & Predictive Maintenance Programs
Unlike conventional multimeters, the DLRO100XB eliminates contact resistance errors by using the Kelvin 4-wire measurement method, ensuring highly accurate and repeatable results that engineers can rely on.
Its CAT IV 600V safety rating, rugged field-ready design, rechargeable battery operation, and data storage capability make it the preferred solution for both field testing and substation maintenance.

Why Rent Instead of Buying?
Purchasing a professional low resistance ohmmeter represents a significant investment—especially if it’s only required during shutdowns, commissioning, annual maintenance, or FAT/SAT activities.
Renting gives you:
✔ Lower project cost
✔ Calibrated and ready-to-use equipment
✔ Immediate availability
✔ No maintenance or calibration worries
✔ Ideal for short-term projects and emergency testing
Pay only when you need it.
