These thermometers are ideal for use in applications where a very precise accurate temperature measurement is required. Thermometers are individually calibrated to NIST standards at specific temperatures and supplied with an NIST report of calibration stating corrections to one-tenth the smallest division.

Thermometers feature triangular anti-roll fitting, permanently fused markings, blue spirit liquid, white background glass; are also individually serial numbered. Include an NIST-traceable statement of accuracy and a triangular-style antiroll fitting.
