Is There Such a Thing as On Site Calibration of Mass Flow Controllers?

Earlier this week we posted the question below about whether anybody in the industry could offer onsite calibration of Mass Flow Controllers. One reader responded saying that he had almost 200 MFC units in his facilities and that when he sent them out for calibration it would typically involve a cost of about $200-$400.00 USD each, so yes he was very curious about whether such a service exists. Alas after a lot of digging and numerous comments it does not appear that anybody in North America can offer an onsite service-damn.

“Onsite Mass Flow Controller Calibration; One of the largest captive heat treaters in North America posed to us a very interesting question, one for which we do not have a good answer; “We are looking for a source to perform onsite mass flow controller calibration to NIST requirements. To date we have not found anybody which can offer this service-does “The Monty” have any good suggestions”. We reached out to a couple of US companies offering calibration and TUS surveys and each said basically the same thing that they do not get enough requests for this service to make it worthwhile. An instrumentation company we approached suggested that they would to this in house but NOT onsite and said that typically the manufacturers of mass flow controllers would offer this service but not in the field. So the question is-are there any companies out there that could perform this service? gord@themonty.com
