Coastal Instruments now has the ability to service MKS Profibus protocol mass flow controllers. We also have a large inventory of these MKS Profibus devices which can be configured to customer specifications and shipped within a matter of days from receipt of order. These type devices are most frequently found in process tools of European origin, especially in optical coating and solar applications. In many cases, replacements and after sales services have been difficult to obtain in the US, until now. Questions? Give us a call at 1-800-632-4357.
