Accreditation

A2LA & ISO 17025

Summary: ThermoWorks is accredited by A2LA to the ISO/IEC 17025 international standard. This certification validates our technical competence and ensures that our calibrations are traceable to national and international standards. Our accredited scope covers specific temperature ranges with uncertainties as low as ±0.005°C.

What is A2LA Accreditation?

Accreditation is an independent certification of a laboratory's quality system and technical competence. ThermoWorks is accredited by A2LA (American Association for Laboratory Accreditation), which assures customers that:

• Our measurements are traceable to national standards (NIST).
• Our methods are scientifically valid and consistent.
• We undergo rigorous assessments every two years to maintain compliance.

Lab Capabilities & Specifications

The ThermoWorks calibration laboratory utilizes high-stability temperature baths and reference-grade instruments to achieve authoritative accuracy.

• Standard Used: ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories).
• Temperature Uncertainty: We can assure calibration uncertainties to ±0.005°C (combined uncertainty).
• Humidity Uncertainty: Humidity calibrations are available with uncertainties to ±0.55%RH.
• Equipment Stability: Our temperature baths maintain stabilities to ±0.001°C.
