Quote: >>E-N-G Mobile Systems has become a leader in the innovation and creation of new specialty vehicle platforms for the ever-increasing, diverse mobile laboratory marketplace, including labs for biological, chemical, and radiological applications.

E-N-G was the first company to install a GC in a mobile lab, and was a pioneer in developing mobile platforms that allowed standard laboratory-grade instruments to be operated successfully in the field. The MobiLab™ product line has raised the level of sensitivity and reliability of analysis done in the field vs. handheld screening devices. It has also made possible significant cost savings in remediation equipment and personnel by providing reliable, on-site analytical confirmation that a project is complete.

Our MobiLab Systems have become the primary choice of mobile labs for scientific and environmental agencies and organizations throughout the country because of their productivity in the field. Each model of our comprehensive line of specialty vehicles, trucks, and trailer systems is custom-integrated with the instruments of your choice, and features a trouble-free electrical system, quality cabinetry and interior finishes, and all appliances. The impeccably constructed interiors are designed for safety, efficiency and ease of use.

Over 400 E-N-G MobiLab Systems are in operation throughout the world. Our laboratory systems support procedures ranging from screening to certified EPA testing methods.<<
