Calibrator Repair: Process, Pressure and Multifunction

Techmaster repairs calibrators: process and loop calibrators, pressure calibrators, temperature calibrators and multifunction electrical calibrators. Because a calibrator is itself a reference standard, it is calibrated after repair and before it is returned, so you can use it again with a current certificate.

We repair instruments from many manufacturers, including older and discontinued models where parts are available. Techmaster is an independent laboratory, not a manufacturer-authorized service center.

Calibrator manufacturers we know best

Techmaster has completed 1,491 calibrator calibrations in the last ten years across 248 instrument lines. These are the manufacturers whose instruments we calibrate most often:

ManufacturerUnits calibrated (10 years)
Fluke731
Ectron250
Omega60
Xitron41
Martel28
Agilent26
Hewlett-Packard25

Common calibrator faults we see

  • Output drift beyond specification over the calibration interval, usually found at calibration rather than in use.
  • Pressure module zero shift or sensor damage after overpressure.
  • Cold-junction compensation faults on thermocouple calibrators, which offset every simulated or measured temperature.
  • Damaged output terminals, failed batteries and charging circuits on handheld units.
  • Display and keypad failures on older bench calibrators.

How does a repair work?

Send the make, model and serial number with a description of the fault and any error codes. We diagnose the fault and send a quote with the expected timeline and warranty terms for your approval. After repair, the instrument is calibrated and returned with its certificate.

What calibration comes after the repair?

The certificate level after repair depends on the functions. Electrical DC and low-frequency functions are on the ANAB ISO/IEC 17025 scope at all four accredited labs, and pressure from −12 psi to 10,000 psi (15,000 psi at San Antonio). Tell us which functions you use so we confirm the certificate level. Exact ranges and uncertainties are on our published accreditation scope.

Need to keep testing while your instrument is away? You can rent calibrator test equipment for the repair period.

Frequently asked questions

Can you repair a process or pressure calibrator?
Yes. Send the make, model and a description of the fault, and we reply with a quote, the expected timeline and the warranty terms.
Why does a calibrator need calibrating after repair?
A repair can change the outputs and readings the calibrator provides. Because you use it as a reference to calibrate other instruments, it needs a current certificate before it goes back into service.
Do you repair Fluke calibrators?
We repair calibrators from many manufacturers where parts are available, including older models. Fluke is the calibrator brand we calibrate most often, followed by Ectron. Send the model, serial number and fault for a quote, timeline and warranty terms.
What if my calibrator is found out of tolerance?
Anything it calibrated since its last good calibration may be affected. Use the as-found data to judge how large the error was, then decide which of those instruments need rechecking. Ask for as-found and as-left data when you send it in.
Is Techmaster an authorized service center?
No. Techmaster is an independent repair and calibration laboratory, not a manufacturer-authorized service center. It repairs instruments from many manufacturers, including older models, where parts are available.
How long does a repair take, and is there a warranty?
It depends on the fault and on parts availability. We include the expected timeline and the warranty terms with the quote.
