When temperature matters is more than a slogan at National Basic Sensor; we are dedicated to being the industries’ source for thermodynamic expertise and temperature measurement products. Included in our manufacturing facility is our state of the art calibration laboratory. We calibrate a wide variety of temperature sensors and products. From common thermocouples and RTD’s, to difficult to calibrate units, like those with non-removable thermowells and mounting brackets, surface temperature probes, large diameter, and angled probes. NBS calibrates to a number of industry standards and maintains an ISO 9001:2015 certified calibration laboratory.
