Certificate of Accreditation Including Scope of Accreditation Below:

Furness Controls has a full service and calibration laboratory at this Indian Trail, North Carolina location.
We provide NIST traceable calibrations in accordance with ISO/IEC 17025:2005 for all of the Furness Controls products. Many of these devices are calibrated on the Furness Controls FRS4 low pressure primary standard. It has an accuracy of better than .01% of reading with a resolution of .01 Pa. (.00004 "H¾O). This primary standard is the only instrument capable of calibrating the full range of Furness Controls products.

Furness Controls offers calibration service for the following:

• Calibrations for low ranges of differential pressure 0.00004 to ±80.000 "H2O. Standard uncertainty is .01% Rdg.
• Calibrations for gauge pressures from 0 to 600 PSI. Standard uncertainty is .01% Rdg.
• Flow calibrations of 1cc/hr to 200 L/min. Standard uncertainty is .5% Rdg..
