Digital Low Resistance Micro-Ohmmeters - DLRO100

About Digital Low Resistance Micro-Ohmmeters - DLRO100

The DLRO100 series is a compact and portable range of digital micro-ohmmeters designed for precise low-resistance measurement up to 100A DC. Using a 4-wire Kelvin measurement method, the series eliminates lead resistance errors, ensuring highly accurate and repeatable results. Ideal for field and workshop testing, these instruments are widely used for electrical maintenance, bonding, and switchgear contact resistance verification. The series includes models for 100A max test current, making it suitable for medium-current applications.
