Electronic Calibration

Electronic Calibration


Measurements of voltage, amperage, or temperature are only valuable if you can place confidence in the device’s calibration.

H&H has state-of-the-art equipment that allows extremely accurate (up to 8ppm) calibration of electronic measuring equipment.

Our highly automated process limits opportunities for human error and reduces turnaround time.

In addition, should sufficient demand arise for additional calibration types, we will entertain upgrading our capabilities, so do not be afraid to ask.

ProCal Software


Our implementation of Transmille’s ProCal software suite provides us with a powerful easy to use complete calibration system. ProCal’s graphical interface provides clear and concise indications of the test status using their “traffic light” system. After each test step the calibration technician is greeted with either green for pass, red for fail, or orange indicating a probable fail or probable pass condition. To pair with ProCal’s clear and concise graphical interface, it also offers automated connection prompts. Which displays on screen graphics to show the technician connection diagrams between the standard and UUT. With ProCal’s exceptional ease of use, this ensures no mistakes are made during the calibration process.

With a central database of automated calibration procedures, the workflow of getting your device calibrated is simplified. The Transmille calibrator is designed to automatically output the values programmed in the selected calibration procedure. Manual selecting values is not necessary. With this advantage, our turnaround time is minimal.

Designed with ISO 9000 and ISO 17025 in mind, ProCal provides us with all the tools to perform automated calibrations and organize data and history for our customers.
