SD Proficiency Testing, LLC

SD Proficiency Testing is an accredited proficiency testing provider in the field of fluid quantities, flow of gases. We have plans in the future, as driven by demand, to add liquid flow, stack and duct flow proficiency testing. Currently we offer flow of gases, up to 1,000 standard liters per minute. We have an artifact with three standards for low flow, up to 50 slpm, a 250 slpm standard, and a 1,000 slpm standard. All calibrated by a laboratory accredited to ISO-17025, and fully traceable to national metrological standards.
