Aoip Instrumentation Digital Ohmmeter 2500 Ω Max, 100 nΩ Resolution, 4 Wire Measurement OM 17

Aoip Instrumentation OM 17 digital ohmmeter provides precise resistance measurement with a maximum capacity of 2500 Ω and an ultra-fine resolution down to 100 nΩ using a 4-wire measurement method. It operates with exceptional accuracy of ±0.05% and a resolution of 0.1 μΩ, enabling sensitive and reliable testing.

This micro ohmmeter supports selectable measurement ranges between 5 mΩ and 2.5 kΩ and can apply continuous or pulse current from 1 mA up to 10 A, with the capability to maintain 10 A continuous current for up to 60 minutes. With a stabilization time of under 2 seconds, it facilitates faster current loading especially useful for coil resistances.

Designed for field use, it includes 2 programmable alarm thresholds with both visual and sound notifications to alert operators. The device compensates for ambient temperature (measured or programmed), performs automatic EMF compensation, and allows metal temperature coefficient compensation ensuring accuracy under diverse environmental conditions.

The instrument includes a memory capacity of 1000 measurements, each identifiable for easy reference. It features a rechargeable Nickel-Metal Hydride battery that delivers battery life sufficient for approximately 5000 tests, enhancing portability for on-site tasks.

Ideal for use across multiple industrial sectors including aerospace, automotive, cable manufacturing, energy fields, electronics, railway maintenance, and telecommunications. It can accurately measure coil, transformer, and motor resistance, perform loss and heat rise calculations, and test contact resistance on low voltage connectors and relays.

Measurements are triggerable manually or automatically with secure locking socket connections to avoid disconnections or errors. The compact, ergonomic instrument measures 270 mm in length, 250 mm in width, and 180 mm in height, with a total weight of 4 kg, suitable for robust field operations.

Applications include electrical component testing, welding quality control, earth bonding verification, cable resistivity and length calculation, and non-inductive resistance measurement. This ohmmeter supports measurement over a wide ambient temperature range from -10°C to 55°C.

The OM 17 model meets industrial need for high precision low resistance measurement. Its portability and accuracy support diverse test and measurement tasks in harsh industrial environments. Robust construction and advanced features make it suitable for laboratory and field applications.
