Critical Environment Technologies
Founded in 1995, Critical Environment Technologies Canada Inc. (CETCI) is a well-established, leading global manufacturer of gas detection systems, including self-contained systems, controllers and transmitters, and Indoor Air Quality (IAQ) monitors.
In early 2007, YES Environment Technologies Inc. was merged with its larger mother company, CETCI, and operates under the CETCI name. The merger allowed for more resources to invest into product development, marketing and service. YES and CETCI products are sold through a network of authorized distributors around the world.
