IET Labs

What IET Labs does

IET Labs, Inc. is a privately held US manufacturer of precision electrical test and measurement instruments, founded in 1976 and headquartered in Roslyn Heights, New York, with a manufacturing and service facility in West Roxbury, Massachusetts. The company specializes in metrology-grade resistance, capacitance, and inductance standards, decade boxes, and meters — including decade resistors (HARS, HRRS, PRS series), decade capacitors (CS, HACS-Z, PCS series), decade inductors (LS, PLS series), resistance standards, LCR meters, megohmmeters, micro-ohmmeters (LOM-510A), RTD simulators, KVD voltage dividers, and stroboscopes. Its products span accuracy classes from budget (sub-$300 substitution boxes) to lab-grade programmable standards (e.g., PRS-370, GenRad 1433) with IEEE, RS-232, Ethernet, and USB interfaces and LabVIEW drivers for automated stations.

The company operates three product identities: original IET-branded instruments, the GenRad legacy line (acquired in 2000 — standards, impedance decades, megohmmeters, digibridges, audio, stroboscopes), and the esi/Electro Scientific Industries resistance line (acquired in 2006). IET Labs manufactures and services all three lines "in the Genrad tradition" and protects certain innovations through US Patent 6487456 (OS-260/OS-270 ohm*SOURCE microprocessor-controlled resistor) and proprietary self-adjusting resistance technology in the PRS-370.

IET Labs sells direct to calibration laboratories, field/industrial users, and educational institutions globally via an e-commerce storefront localized in 11 languages, with request-for-quote flows for higher-value and custom instruments. Recurring revenue is generated through an A2LA-accredited calibration laboratory (Certificate #2073.01) offering NIST Traceable, Z540, and ISO-17025 accredited calibrations and repair services for IET, GenRad, esi, and third-party instruments. The company is privately held with no disclosed institutional investors, no external funding events, and an employee headcount reported in the 11–50 range.
