About Ohm-Labs
Ohm-Labs was formed in 2006 by the former president and quality manager of Process Instruments, Inc. to focus solely on the manufacture of resistance standards, precision current shunts, high voltage dividers, wire-wound resistors, and instruments based on resistors.
Ohm-Labs acquired the resistor manufacturing capabilities of Process Instruments, including those formerly held by Leeds & Northrup and Julie Research Laboratories. Ohm-Labs continues to support these products and can provide them by special order. Ohm-Labs is dedicated to advancing the state of the art of resistor manufacturing.
Ohm-Labs welcomes existing and potential clients to discover solutions in all areas of resistance.
"Excellence in Resistance" is our mission. All our products are made in the USA.
Our Commitment to Quality
Ohm-Labs' quality control system is accredited by the American Association of Laboratory Accreditation (A2LA) to ISO17025, which includes the ISO9000:2000 standard. High voltage AC has recently been added to our scope.
