Frequently Asked Questions



How long will it take to Calibrate my equipment?

Equipment Calibration or repair time is based on a variety of factors including workload, parts availability, and repair complexity. Generally speaking, our service turnaround times average 3-5 business days for calibration and 11-14 days for repair. This turnaround time is inclusive of the time it takes to get your unit evaluated and the time it takes to repair it from when it was approved.

Do you offer expedited service?

Service can be expedited for a small fee. This will place your equipment next in line for service and speed up turnaround time dramatically.

What are your calibration expedition fees?

Expedite fees vary depending on the instrument. Please consult with our sales representative for pricing at

Do you offer pickup and delivery service?

Yes we do offer pickup and delivery services within Texas. Please contact our sales representatives at  for specific information about availability.

What if my instrument cannot be calibrated?

If your instrument cannot be calibrated due to an instrument failure, you will be notified to determine how you would like to proceed. A number of different options may be available including repair of the instrument by us at our Houston Repair Center, repair by the original equipment manufacturer (OEM) if applicable, or we can provide a quote for a replacement instrument.

Can you provide me a recommended calibration interval for my instrument?

We would be happy to provide you with assistance if needed. However, we cannot recommend a calibration interval. You must choose a calibration interval based on your company’s quality policy and the performance of the instrument over time. There are a number of factors that need to be considered when determining your calibration interval. We will be glad to guide you through this process.

Is my calibration certificate available in an electronic copy?

Yes, your calibration certificates will be stored for at least 3 years at no additional charge.

What are the different levels of Calibration you offer?

We offer three levels of calibration service: Certificate of Calibration, Certificate of Calibration with Data, and Certificate of Calibration with Data and Uncertainties. These are available through our calibration asset management system web portal.

Where is your calibration laboratory located?

We are located in Houston, Texas USA.

What types of instruments do you calibrate?

We calibrate a wide variety of instruments across a number of disciplines including electrical, temperature, pressure, dimensional, humidity, torque, flow and many more. Please see this overview of our capabilities for a complete list.

Do you have a calibration management program?

Yes, we have a comprehensive calibration and asset management program called CAMS, which stands for Calibration Asset Management System. We will automatically remind you a month before your next calibration is due.

Can I specify points for my calibration?

Yes you can specify which points are used for your calibration. There may be an additional charge depending on the points requested and the discipline of the calibration. The calibration may also be considered a “limited calibration” if the test points requested do not test the entire function/range of the instrument.

Will the cost change if I change the calibration interval?

Your specified calibration interval has no bearing on the price of your calibration. Each customer sets their own calibration intervals.

If I change my calibration interval to two years instead of one year does my price change?

Your specified calibration interval has no bearing on the price of your calibration.

Each customer sets their own calibration intervals.

Do you offer a NIST traceable calibration? All I see is accredited calibration.

Generally, all of our calibrations are traceable to a higher authority such as NIST. NIST is a National Measurement Institute (NMI), but is not the only NMI capable of providing traceability.

What are “uncertainties” and why would I need them?

uncertainties define how well a lab can perform a respective measurement, the lower the uncertainty the better the measurement. Uncertainties are all inclusive of respective processes to include traceability components. Please click here to see our white papers.

Is “as found/as left” data necessary?

Measurement data isn’t absolutely required but it is highly recommended for most quality programs. This data enables the user to determine where within its respective tolerance requirements the instrument was found and was returned to the customer. This is especially important when the unit is found out of tolerance.

What makes you different from any other calibration provider?

TestEquipment USA invests significantly in operations and quality control departments to ensure our systems and processes are correct. We have a robust technical & quality team that develop calibration processes and verify those processes on a regular basis.

All I need is a cal sticker, what difference does it make who I use?

If you are making measurements it’s important that you have confidence that those measurements are correct. If not what’s the point in measuring?

Do I need to have my equipment calibrated regularly?

Almost always, but the frequency of recalibration varies depending on the measurement and Test Equipment.This interval is usually defined by the original equipment manufacturer (OEM) but can be adjusted based on the stability of the respective equipment.

Do I need documented uncertainties with every accredited calibration?

Per the International Laboratory Accreditation Cooperation (ILAC) P14 you must have documented uncertainties to continue traceability.
