I need a Market Analyst to understand the size of the sales market for equipment that can replace the Fischer sub-sieve size measurement equipment in ASTM - B330

Standards groups with specific standards (ASTM B330 & ISO 10070) are seeking alternative pieces of equipment for the current specified Fisher SSS unit which are no longer being manufactured. We are seeking to understand if it is worth trying to develop an alternative piece of equipment by understanding the potential market size for replacement equipment.
