T&R Test Equipment
DMO200 Digital Micro-Ohmmeter

The DMO200 Digital Micro-Ohmmeter is a highly versatile and reliable device designed for precise measurement of low resistances. It excels in various applications, making it suitable for commissioning, maintenance, and production line environments. Additionally, it enables efficient and safe measurement of contact resistances in circuit breakers, switch panels, isolators, and busbar joints.

The unit offers the convenience of presettable test currents, allowing users to store commonly used settings for quick access. Moreover, range selection is fully automatic, ensuring accurate measurements at all times. The simultaneous display of current, voltage, and resistance provides comprehensive insights.

T&R Test Equipment
DMO600 Digital Micro-Ohmmeter

The DMO600 Digital Micro-Ohmmeter is simple to operate, and automatically maintains desired output current. Output current, voltage and resistance are all displayed simultaneously. The DMO600 uses a four wire Kelvin connection to measure low resistance. The resistance is calculated from the test current and sense voltage. 

The unit can output any current from 10A to 600A, and has the option of three pre-programmable test currents, which can be selected at any time.

    • 10-600A DC test current with <2.5% ripple

    • 0.1μΩ resolution

    • mV, A, and m/μΩ displayed simultaneously

    • USB memory key for data storage

    • USB keyboard for comment entry

    • Pre-settable test current with three buttons to store user test currents

    • Large back-lit liquid crystal display

    • Universal supply voltage 90-264V

    • Supplied with 3m output lead set

    • Optional current clamp to allows testing of objects with both sides earthed
