Dear Mr. Barrett

Thank you very much for the prompt response on SGS request to clean and inspect Fume Hoods Ventilation at Bridgeport, NJ location.

I was very pleased how professionally and well organized IMC has performed this service.
All service was done without even slowing down our daily business.

I would highly recommend using IMC for all inspection, cleaning or Aircuity test projects.

Sincerely,

Sam Kleynman.
Laboratory Manager.
