AOIP OM21 Programmable Benchtop Micro-Ohmmeter – High Accuracy: 0.03 %

Features

The OM 21 programmable table micro-ohmmeter is intended for 4-wire measurement of very low resistance resistances up to 20 kΩ with an excellent maximum accuracy of 0.03% and a resolution of only 0.1 µΩ. The reliability and the precision of the measurements is reinforced by the low temperature coefficient (10 ppm / ° C), the automatic compensation of the electromagnetic forces before each measurement carried out, the temperature compensation of the nature of the metal and the room temperature compensation.

AOIP OM21 is a programmable table micro-ohmmeter designed for 4-wire measurements of very low resistance up to 20 kΩ. It boasts an impressive maximum accuracy of 0.03% and a resolution of just 0.1 µΩ. The reliability and the precision of the measurements is reinforced by the low temperature coefficient (10 ppm / ° C), Its reliability and precision are ensured by features like low temperature coefficient (10 ppm / ° C).

AOIP OM21 offers three measurement current options – continuous, pulsed, or alternating – ranging from 100 µA to 10 A. It’s versatile in start-up and sampling conditions, making it suitable for various sectors and applications. It can measure resistance and resistivity of cables, inductive resistances like motor coils and transformers, contact resistance of connectors and switches, test low-power electrical components such as fuses, and assess devices responsive to temperature. It’s also useful for metallization control, earthing, and checking earth continuity.

AOIP OM21 is user-programmable, either directly on the device or through LOG OM software. It allows customization of measurement settings, alarms, and storage options. It can save up to 1000 measurements in its memory for later review on the device or a PC. No internal adjustment is needed for electronic calibration. For repetitive measurements, AOIP OM22 is recommended for test bench use, offering similar features but with 6 preset configurations for convenience.
