Calibration Lab

sample-documentationNational Basic Sensors’ in-house calibration lab can supply N.I.S.T. traceable calibration on all thermocouple and RTD assemblies. Our state of the art calibration lab maintains SPRT and thermocouple reference standards and has facilities to calibrate over a temperature range of -78°C to 1454°C. We calibrate a wide variety of temperature sensors and products from common thermocouples and RTD’s, to difficult to calibrate assemblies. In addition, NBS calibrates to a number of industry standards and maintains ISO 9001:2015 certification and 17025 compliance.
