Chroma 16502 Milliohm Meter

0.001mΩ - 1.9999MΩ

The Chroma 16502 Milliohm Meter measures low resistance from 0.001mΩ to 1.9999MΩ with ±0.05% accuracy using a Kelvin 4-wire method to eliminate lead resistance errors. It features pulsed, DC, and dry-circuit test modes, along with temperature compensation for precise measurements. The meter supports fast measurement speeds (65ms), programmable pass/fail evaluations, and automation interfaces (RS-232, optional GPIB & Handler) for production and quality control applications. It is used for contact resistance, coil winding, PCB trace, and conductive material testing in electronics, automotive, and industrial applications.
