Support - Repair and Calibration

A tool is only as good as the service is to keep them going. When a tool goes down or just needs to calibrated quick professional service is a must.


Calscan team of experts technician will repair all Calscan tools and accessories. Tools are usually fixed within 14 days of receiving them.


Calscan facilities calibrate electronic pressure, temperature recorders to US and Canadian standards. All our calibration equipment is traceable to the National Institute of Standards and Technology (NIST).

All our tools use a multipoint calibration over a range of temperatures and pressures. For example a 1500 psi Falcon would be calibrated with 7 pressure steps at each of 5 temperatures for over 35 calibration points.

Temperature °C

-40 °C

-15 °C
0, 250, 500, 750, 1000, 1250, 1500
10 °C
0, 250, 500, 750, 1000, 1250, 1500
35 °C
0, 250, 500, 750, 1000, 1250, 1500
60 °C
0, 250, 500, 750, 1000, 1250, 1500


More accurate tools like the Hawk have even more calibration points. This data is then used to produce a digitally compensated tool, that has high accuracy's that will carry through even during temperature transitions, where simple two point calibrated tools will fall way out of its specification.

Primary Pressure Reference Standards

At Calscan we go way beyond government requirements Our best DHI deadweight has an accuracy of over ±50 ppm and is calibrated by a accredited lab that is NIST traceable. We then use this deadweight to check all the others. You can view the calibration certificate here.

Temperature Ovens

Stable and accurate temperatures are also critical for a good calibration. Calscan has many ovens depending on the need to calibrate our tools in.

  • Seven custom designed hot oil bath ovens for temperature calibration of downhole recorders, providing extremely stable temperatures.
  • Four refrigerated environmental chambers which give us the capability of calibrating in extreme temperatures from -75 to 250 degrees Celsius.
  • Two high temperature chambers which give us the capability of calibrating and testing from 30 to 300 degrees Celsius.
