What our customers are saying


I am sending this short note to praise you on the excellent technical service I recently benefited from when I needed assistance on fixing a problem with a mass flow meter I bought a while ago from your company. The people whom I talked to were very professional and the entire experience exceeded my expectations. I would like to mention specifically the name of Joe Ancona who gave me a very valuable advice over the phone on how to solve a technical problem and assisted me with spare parts, which were sent to me very quickly, so that I could return the unit to an working condition in no time.

I can honestly say that I never received a better service of the same nature from any other business units although I’ve been dealing extensively with a variety of them for over 10 years.
