Micro-Ohmmeter DLRO 200

Adiradh offers the Micro-Ohmmeter DLRO 200 as a precise instrument for low-resistance measurement in electrical systems. Moreover, it is designed to measure micro-ohm values accurately under field and laboratory conditions. Therefore, it supports maintenance, testing, and commissioning activities effectively. In addition, the DLRO 200 uses high test current to reduce contact resistance influence. Also, it delivers stable and repeatable readings for critical joints. Furthermore, the instrument is suitable for substations, plants, and workshops. However, its operation remains simple and safe for technicians. Consequently, testing time is reduced without compromising accuracy. As a result, engineers can quickly identify loose or degraded connections. Thus, system reliability improves during routine inspections. Finally, the Micro-Ohmmeter DLRO 200 integrates robust construction with clear measurement display, making it a dependable solution for professionals who require accurate low-resistance testing across a wide range of electrical assets.

Overview 

The Micro-Ohmmeter DLRO 200 is designed for accurate measurement of very low resistance values. Moreover, it applies a high DC test current, typically up to 200 A, to ensure precise results. Therefore, it minimizes the effect of contact resistance and surface oxidation. In addition, the instrument supports testing of breakers, busbars, joints, and bonds. Also, it provides clear digital readings for easy interpretation. Furthermore, the DLRO 200 is portable, which allows flexible use at site locations. However, it maintains measurement stability even in harsh environments. Consequently, maintenance teams can rely on consistent data. As a result, fault detection becomes faster and more reliable. Thus, downtime during inspections is reduced. Finally, the DLRO 200 supports preventive maintenance programs by enabling early detection of abnormal resistance increases in critical electrical connections.

About Product

The Micro-Ohmmeter DLRO 200 is a high-current, low-resistance measuring instrument used for micro-ohm testing. Moreover, it operates using the four-terminal Kelvin measurement principle. Therefore, lead resistance and contact errors are effectively eliminated. In addition, the device generates a controlled DC output current up to 200 A. Also, it measures resistance in the micro-ohm range with high resolution. Furthermore, the internal circuitry includes current regulation, voltage sensing, and digital signal processing. However, the instrument remains compact and field-ready. Consequently, it is suitable for on-site diagnostics of conductive paths. As a result, it supports testing of circuit breaker contacts, switchgear joints, and grounding connections. Thus, engineers obtain accurate resistance values that comply with electrical maintenance standards. Finally, the DLRO 200 is engineered for durability, accuracy, and repeatable performance.

Technology & Benefits

The Micro-Ohmmeter DLRO 200 uses high-current injection technology for low-resistance measurement. Moreover, the four-wire Kelvin method separates current and voltage paths. Therefore, measurement accuracy improves significantly. In addition, digital processing ensures stable and noise-free readings. Also, the regulated current output maintains consistency during tests. Furthermore, the clear display supports quick data interpretation. However, safety circuits protect both operator and equipment. Consequently, testing can be performed confidently in live environments after isolation. As a result, measurement errors caused by poor contacts are minimized. Thus, maintenance decisions are based on reliable data. Finally, the combination of high current, precise sensing, and rugged design provides long-term operational benefits for electrical testing and preventive maintenance programs.
