It is with great pleasure that I recommend Mr. Charles Luchessa and his firm SM Technical Consultants Inc. Their firm did the installation and training in Cali Colombia for CVC's Mobile Air Quality Monitoring System. Mr. Luchessa worked in our facilities in Cali, assembling, installing, and connecting the components of the unit, which was made up of meteorological sensors, and automatic particulate and gas analyzers. It also contains a complete calibration and data recovery system. His work was very successful. The monitoring unit was completely set up and the personnel trained for its operation. Given the opportunity, our company will certainly hire Mr. Luchessa and his firm for jobs related with the design and installation of monitoring networks.
Sincerely,
