National Basic Sensor

Since our founder built his first thermocouple in the garage of his Philadelphia row house in the early 1900′s, we have strived to achieve the utmost in customer satisfaction. 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 9001:2008 certified calibration laboratory.
