Timeline
- 1946 – Edgar Sharpe establishes a machine shop under the name Sharpe Instruments Limited to “produce fine mechanical instruments and components.” In collaboration with Arthur Brant, a Professor of Geophysics at the University of Toronto, he designs and manufactures a vertical force magnetometer. “Sharpe Instruments also acquired the technology of a quartz element gravity meter and started to produce it.” (“History”)
- 1947 – “Sharpe Instruments” is located at 188 George St., Toronto, ON. Listed under mining equipment. (Might’s Greater Toronto City Directory (1947))
- 1961 – Sharpe Instruments goes public as E.J. Sharpe Instruments of Canada, Ltd. (“History”)

- 1982 – The company purchases the Cesium High Sensitivity Magnetometer division of Varian Associates Inc. (“History”)
- 1988 – The company purchases the Earth Science Division of EDA Instruments Ltd., acquiring a line of exploration, seismology, and radon detection and monitoring instruments. (“History”)
- 1988 – Cesium vapour magnetometer, proton precession magnetometer and Vector fluxgate magnetometer listed as instruments presented at the International Workshop on Magnetic Observatory Instruments. (Geological Survey of Canada)
- 1989 – The company, now known as Scintrex, develops “a quartz-based relative gravimeter, the CG-3, based on the PhD thesis of Dr. Andrew Hugill, who was Scintrex’s Director of Engineering.” (“History”)
- 1999 – Merges with Micro-g Solutions of Denver and Auslog Pty. Inc, “an Australian-based borehole logging company.” (“History”)
- 2001 – The company merges with LaCoste & Romberg, a company based in Austin, Texas, USA, a producer of relative gravimeters. The new company is known as LaCoste & Romberg – Scintrex, Inc. (LRS, Inc.), and operates out of Concord, ON. (“History”)
- 2024 – Scintrex is active and developing new instruments, listed as a division of “LRS”, located at 222 Snidercroft Rd, Concord, ON. (https://scintrexltd.com/)
