HIOKI RM3546 Resistance Meter (Nanohm-Level Low Resistance Meter)

תיאור

The HIOKI RM3546 combines nanohm-level sensitivity, robust safety features, and intelligent compensation functions to deliver stable, reliable resistance measurements even in challenging industrial environments. Its capabilities make it a top choice for customers focused on quality assurance, safety, and manufacturing efficiency in battery and power electronics sectors.

✔ Ultra-High Precision Nanohm Measurement

1 nΩ resolution within a 1000 µΩ range captures the smallest resistance changes.

Detects subtle defects in welds and low-resistance joints used in battery packs and power electronics.

Reduces false readings by compensating for thermal noise.

✔ Advanced Offset Voltage Correction (A-OVC)

Suppresses thermal EMF and voltage offset to improve measurement stability even under variable temperatures.

Ensures consistent, repeatable data across lab and production environments.

✔ Active Circuit Protection (ACP)

Built-in safety protects the instrument from accidental DC input up to 60 V, minimizing downtime.

Enhances reliability in high-voltage production settings

✔ Broad Path Resistance Tolerance

Up to 9 Ω path resistance tolerance in 500 mA mode enables flexible wiring layouts and long cable runs on inspection systems.

Ideal for inline testing with multiplexer systems.

✔ Advanced Temperature Compensation (A-TC)

Automatically compensates resistance measurements to a reference temperature, delivering accurate results immediately after welding.

Shortens takt times and supports fast production workflows.
