RS 81.B RS 81.W
Features Calibration performed at Webber Gage in Cleveland, OH. Certificate of Calibration with NVLAP® accreditation. Calibration in accordance with ISO 17025
with dated calibration certificate and NIST traceability number. The name and address of the user may be added to the calibration certificate. Inch System (RS 81.B) uncertainty of measurement (k=2): U = 6 + L where L is in inches, but U not less than 7 min. Metric Systems (RS 88.MB & RS 112.MB) uncertainty of measurement (k=2): U = 0.15 + .001L where L is in millimeters, but U not less than 0.18 μm.
Calibration performed in China in partnership with Webber Gage. Webber Gage samples the measurements to monitor the calibration results. Calibrations are traceable to NIST, but no NIST traceability number or dates will be given. The name and addrress of the user will be left blank on the calibration certificate. Inch System (RS 81.W) uncertainty of measurement (k=2): 10 µin. Metric Systems (RS 88.MW & RS 112.MW) uncertainty of measurement (k=2): U = 0.25 µm.
