Welcome to Ohm-Labs

Ohm-Labs is the only U.S. company to focus exclusively on resistance. We work to continually improve the performance, accuracy, and stability of our metrology-grade standards.

Ohm-Labs manufactures standard resistors from 10 micro-ohms to 10 teraohms; precision current shunts and high voltage dividers.

All products are supplied with ISO 17025 accredited calibration.

Ohm-Labs' mission is "Excellence in Resistance".
