As a matter of fact, JCTM do not only supplies international products like many types of sensors, analyzers, monitors, dataloggers and so on, coming from several internationally well concepted companies around the world, some of them represented by our group.

We also produce part of what we supply, through our 50 square meter production area. Some of these equipment’s are mechanicals as winches, rain gauge, sediment samplers, meteorological housing, fluviometric weight, totalizer anemometer, etc.

In most of its supplies, JCTM indeed integrates the imported instruments one to another, besides several complementary accessories manufactured by its production, thus, allowing customers the required assurance that the whole system will be handled by only one company, as well as its knowledge and responsibility.


As a great differential into market, JCTM counts with engineers and technicians in two essential areas – supplying and new projects; and technical Assistance. Thereby, our technical group has the ability to support customers before, in the meanwhile and after delivering. This makes indeed clients so much comfortable and, thus, satisfied.

Our technical group is a 10+ years of experience, what guarantee high knowledge and confidence. We are able to lead new challenges year by year and, mainly, growing our customer portfolio.

We are in all phases of a product life cycle: Development, homologation, start-up, operating and maintenance of the system, not only regards intrinsically to the instrument, but also to all parts of the system composition, due to our expertise in the core of system, but also around it.


This a bit over what JCTM is known in Brazil, a serious company, that never is satisfied with its present, but thinking how much it’s possible to improve it, instead. Send us your question by filling out the following link.
