Test switches manufactured in Lachine Quebec
A test switch may be a small part of a metering installation, but selecting the right configuration matters. Utility specifications, connections, mounting requirements and maintenance practices all influence the choice. Mesurina brings Canadian test-switch manufacturing and local customer support together to help utilities address those requirements.
Our Lachine facility manufactures metering test switches, also known as test blocks, for the Canadian utility market. The team also handles assembly, purchasing, receiving, servicing, sales and distribution under TESCO’s certified quality management system.
For purchasing teams, that provides a Canadian point of contact for product requirements and order coordination. For metering teams, it provides access to people who can discuss the application and connect it with the broader TESCO portfolio.
