CalibrationWhat's the cost of
an uncalibrated scale?

JP Bowlin has a climate-controlled calibration laboratory, and our team of professionals has an average of 15 years of experience to handle your calibration needs.  Most equipment calibrations can also be performed on-site at your location if you prefer.

JP Bowlin’s services are designed to ensure that our testing methods meet or exceed the requirements of standards such as ISO/IEC 17025, ASTM, NIST HB44 and Weights & Measures Commercial Usage. We offer NIST traceable calibrations depending upon the equipment and customer needs, and customers can access our password protected on-line calibration certificate system as well.
