Ensuring Measurement Accuracy Through Calibration
STN Instruments offers comprehensive in-house and onsite calibrations, including temperature calibration services covering a wide range of instruments, including thermometers, RTDs, thermocouples, temperature transmitters, and data loggers.
Key features of STN’s calibration capability:
-
Wide Temperature Range: -195.8 °C (liquid nitrogen) to +250 °C (liquid and dry-block systems)
-
High Accuracy: Uncertainty as low as ±0.015 °C for comparison calibrations
-
Standards Traceability: SI Units through NIST by unbroken measurement chain
-
Experienced Technical Team: Over 24 years of metrology experience in temperature measurement and calibration
STN has demonstrated its technical competence through participation in proficiency testing, including a 1/4" PRT thermometer proficiency test where STN achieved satisfactory results with measurement uncertainties between 0.015 °C and 0.03 °C from -30 °C to 200 °C.
These results confirm that STN’s calibration methods, reference standards, and technical procedures align with the best practices of accredited calibration laboratories.
