Calibration Procedure for Liguid In Glass

NIST traceable primary reference standards are used in accordance with PTC Metrology's ISO/IEC17025 compliant procedures which also meet the requirements of ISO 9000 series quality standards. The unit under test (UUT) is inspected under polarized light utilizing a Polariscope for stress; the capillary is inspected under magnification to check for contaminates and discernible irregularities; and the UUT is held at 23°C for 72 hours. The UUT is compared with standard thermometers held by PTC Metrology. All measurements are traceable to NIST. The temperature scale used is the ITS-90 and all readings are in degrees Celsius unless noted. PTC Metrology is an A2LA accredited laboratory for temperature calibration.

Certifications will include as received and as returned data, a statement of uncertainty, laboratory conditions, and information on the primary standards. Minimum charge per instrument tested is $80.00
