Ideal for measuring inside diameter, outside diameter and depth
- Stainless steel or carbon fiber models
- Zero at any point
- Switch between inches and millimeters
- NIST traceable
Thomas Traceable digital calipers take length/diameter measurements three ways: outside, inside and depth. Carbon fiber models never require lubrication on the ultra-smooth slide bar. Easy to read digital display is 1/3” inch high.
Precision calipers are ideal for measuring the OD of stoppers, the ID of tubing and the depth of vials. This permits a Floating Zero or reference point to read “greater than or less than results with a minus sign displayed” without calculations.
To assure accuracy, units are provided with an individually serial numbered Traceable certificate from an ISO 17025 calibration laboratory accredited by A2LA. Certificate indicates traceability to standards provided by NIST.
Please note: The aforementioned A2LA accreditation belongs to the manufacturer, not Thomas Scientific.
