Southwest Calibration Service, Inc.

Southwest Calibration Service, Inc. (SCS) was founded in 1988 dedicated to fulfilling two goals: continually meet or exceed our customers’ quality needs as well as building a lasting working relationship.

Our primary business is the calibration of dimensional, electronic and physical inspection, measuring and test equipment (IM&TE). We also have the capability of repairing your equipment. Another service provided by SCS is the selling of new equipment with SCS calibration certificates. In order to maintain our standards of excellence, 99% of our calibrations are provided by SCS personnel either in our Stafford-based facility, southwest of Houston, or at our customer’s location.

Southwest Calibration has been an ISO/IEC 17025 Accredited Laboratory since 2007. All calibrations are traceable to NIST or other National Standards where such standards exist. Thanks to our well equipped mobile teams we are able to perform many of our services both on and off site.

What's New at SCS:

SCS has recently acquired the new Fluke 6003A Three Phase Power Calibrator

  • The 6003A enables us to calibrate three phase power meters 18 kVA @ 1 kHz on each phase, as well as power quality meters and energy measurement devices.
  • A combination of the 6003A high current output and our new current coils allows us to test clamp meters up to 2,250 A AC/DC, and  flexible current probes up to 4,500 A AC/DC.

With the recent addition of the Mahr Linear 2000 Universal Length Measuring Unit, we have increased our capability to calibrate micrometer standards up to and including 79 inches.
