What Refraction Technology does

Refraction Technology, operating as REF TEK, is a Canadian specialty manufacturer of high-resolution seismic monitoring instruments headquartered in Dartmouth, Nova Scotia. Founded in 1975 by Paul Passmore, the company designs and produces broadband seismic recorders (Wrangler-HDR, Wrangler-S), integrated recorder/accelerometer systems (SMHR2, SMA2), multi-channel recorders (180-MC), broadband seismometers (Colt, Colt-PH, 151D Bronco), and a range of uniaxial and triaxial accelerometers (131D-01/1, 147A, 131D-BH). Core technologies include 32-bit A/D conversion, force-balance feedback sensors, MEMS capacitive accelerometers, IP67/IP68 environmental sealing, and proprietary telemetry protocols (RTP, SEEDLink). The product portfolio expanded in December 2023 with the acquisition of Lennartz Electronic's IP, adding the LE-3Dlite MkIII, LE-1D/Vlite MkIII, LE-3D/BH(s) MkIII, and LE-3D/5s MkIII seismometers.

REF TEK serves four primary verticals: seismological research institutions, structural health monitoring operators, hazard mitigation/emergency management agencies, and critical infrastructure operators (hospitals, dams, bridges, nuclear plants). The customer base is overwhelmingly governmental or quasi-governmental, including the China Earthquake Administration (478 Wrangler recorders), India Meteorological Department (EEW backbone), Aswan Dam Authority, BC Ministry of Transportation (Port Mann Bridge), and the IRIS/PASSCAL consortium (~30% of Global Seismographic Network stations). With 7,000+ instruments deployed across 30+ countries and a 40-year deployment record at the ANZA network, the company has established a durable installed base in scientific and regulatory monitoring.

The business model is hardware-centric, generating revenue through direct equipment sales (recorders, sensors, accessories), software licenses (COMPASS, RTI Suite, mobile apps), and professional services (system design, commissioning, training, support). Go-to-market combines direct enterprise sales in Canada/USA with a global network of regional distributors and channel partners across Latin America, Europe, Asia Pacific, the Middle East, and Africa. Pricing is quote-based and not publicly disclosed; standard warranty is 12 months with optional extensions. The company has received non-dilutive growth capital from the Atlantic Canada Opportunities Agency ($420,375 in 2021; $194,461 in 2026). The firm is privately held by Reftek Systems Inc., with leadership shared with sister company Xeos Technologies Inc.
