What Ohm Labs does
Ohm-Labs, Inc. (Ohm Labs) is a Pittsburgh, Pennsylvania-based designer and manufacturer of precision electrical metrology instruments, founded in 2006 as a spin-off from Process Instruments (which itself traces to 1985). The company produces resistance standards, precision current shunts, and high voltage dividers, serving calibration laboratories, national metrology institutes, and industrial measurement customers worldwide. It holds ISO 17025 accreditation through A2LA and Nupic qualification for nuclear-industry customers, indicating compliance with formal metrology and nuclear-quality standards. Founder Jay Klevens leads a team of 11-50 employees.
Ohm Labs' product lines include guarded high resistance standards (with more than 500 units delivered cumulatively), high-value standard resistors, precision current shunts such as the CSA coaxial AC shunt series, and the HVS high voltage divider series. The technology is built on heritage designs acquired from Leeds & Northrup (1994, via Process Instruments), Julie Research Labs, and EIS/Sensitive Research (2010), and is protected in part by US Pat. No. 6,798,214 covering a SmartResistor concept. The modular construction of its resistance standards allows customers to stack adder units to extend resistance ranges, supporting a flexible configure-to-order offering.
The company operates a B2B distribution-led model, selling through a network of more than 25 distributors across 30+ countries. Revenue is generated through direct unit sales of high-priced precision instruments (typically thousands to tens of thousands of dollars per unit) to a long tail of calibration laboratories and metrology institutions. The business is privately held, founder-owned, and shows no disclosed outside funding, with growth funded organically through operations.

Ohm Labs product offering
Product offeringCore offering
Ohm Labs manufactures precision electrical resistance measurement instruments, including resistance standards, precision current shunts, and high voltage dividers. The company produces physical hardware used by calibration laboratories, national metrology institutes, and industrial measurement operations to establish and maintain electrical measurement traceability. In addition to manufacturing, Ohm Labs provides calibration services for its instruments.
Product overview
Ohm-Labs manufactures precision resistance measurement instruments as a portfolio of specialized, standalone products rather than an integrated platform. The product line centers on resistance standards (from 1 micro-ohm to 10 Tera-ohm), precision current shunts (less than 1A to 3000A), and high voltage dividers (up to 150 kV), all supplemented by calibration services and resistor-based instruments. Resistance standards include the 2000 Series (oil-filled primary standards), 1000 Series (air standards), 200 Series and 100 Series reference standards, Hamon Transfer Standards, One Ohm Standard, and high resistance products (100-H, MHS, MRS, 700 Series). Current shunts comprise the MCS Multiple Current Shunt, CS Series calibration shunts, CSW Working Standard Shunts, and CSA Coaxial AC Shunts. High voltage dividers include the HVS High Voltage Standard, HVT AC Inductive Divider, KV-A portable dividers, and KVVB compact dividers. Legacy products from acquired Julie Research Labs and EIS/Sensitive Research lines are also supported. All products include ISO 17025 accredited calibration.
