Thunder's Calibration Laboratory
Thunder Scientific achieved its NVLAP accreditation in June of 2003 through the National Voluntary Laboratory Accreditation Program (NVLAP) and has maintained NVLAP accreditation ever since. Thunder Scientific is currently the only NVLAP accredited source to offer humidity calibrations that are traceable to the International System of Units (SI) through a national metrology institute (NIST) recognized through a CIPM MRA with uncertainties at (0.17 % * Rdg) + 0.016 %RH*. Thunder Scientific provides SI traceable calibration service on virtually any type of humidity, frost/dew point, temperature and pressure measuring/generating equipment. Final calibration, test and certification are performed in an environmentally-controlled calibration laboratory and NVLAP accredited Certificates of Calibration with Statements of Conformance are delivered with each instrument stating SI traceability. In addition to routine calibrations, Thunder Scientific can provide special test design with automated test sequence for evaluation of sensor performance and stability analysis. We deliver on time service (Expedite service is available) with defect free documentation as per the guidelines of ISO/IEC 17025:2017 and ANSI/NCSL Z540-1-1994; Part 1.
