Company information

Critical Environment Technologies Canada Inc. (CETCI) is a leading global supplier of gas detection systems, including self-contained systems, controllers and transmitters, and Indoor Air Quality (IAQ) portable instruments.

In early 2007, YES Environment Technologies Inc. was merged with its larger mother company, CETCI, and operates under the CETCI name. The merger allows 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.

CETCI gas detectors are used to detect many different gases. Some of the most common are Carbon Monoxide, Carbon Dioxide, Nitrogen Dioxide, Nitric Oxide, Ammonia, Chlorine, Ozone, Combustible Gases like Methane and Propane, Oxygen, Refrigerants and more.

Applications include commercial, institutional, municipal and light industrial markets worldwide. Many of these applications are for vehicle exhaust, but areas of specialization include refrigeration plants, commercial swimming pools, water purification, arenas, wineries and breweries, waste water treatment and many more.

Ongoing product development ensures that CETCIs equipment is at the leading edge of a rapidly evolving technology.
