Calibration Made Easy: 7 Questions for Choosing the Right Lab for Test & Measurement Equipment
Wondering where to calibrate test and measurement equipment? In this article we dive into the different questions you should be asking to assess the reliability and quality of the calibration lab you choose.
In test and measurement, accuracy is everything. You may work in aerospace, defense, biotech, life sciences, or telecom. Any field that relies on precise measurement has the same need. Your instruments must be calibrated to NIST standards. That part is non-negotiable. This is where calibration labs come in. But there are many labs to choose from. So how do you pick the right one? At NSCA & TraCal, we know this decision matters. Below are the questions we hear most often. Consider the following questions:
Is the calibration lab ISO 17025 Accredited?
First, look for labs that hold ISO 17025 accreditation. This accreditation is a mark of quality. It shows the lab meets strict standards for competence and impartiality. Your own rules may not require ISO 17025 calibration. Even then, an accredited lab gives you more confidence in the work.
What's on the calibration lab’s Scope of Accreditation?
Always check a lab’s scope of accreditation. This document is the heart of the matter. It lists the exact equipment and measurements the lab is certified to calibrate. Some labs cover a wide range. Others focus on a narrow niche.
Does Their Scope Fit Your Needs?
Read the scope and match it against your own equipment. Your work may involve RF, microwave, electrical, mechanical, optical, dimensional, or temperature measurement. In every case, make sure the lab can calibrate your exact devices. Check that it has both the skill and the standards to do so.
What is the Depth of Calibration Coverage?
Categories alone are not enough. Look at the depth of coverage in each area. Say you work with RF and microwave equipment. Can the lab reach the frequency range you need? Most labs only cover lower frequencies. Tra-Cal is one of few labs outside of OEMs that can calibrate up to 50 GHz. The same rule applies to pressure and temperature. Verify that the lab can handle your range and your accuracy levels. Study the scope of accreditation closely. It is the clearest proof that a lab can meet your needs.
What's the Turnaround Time?
Time often matters as much as accuracy. Ask each lab about its turnaround time before you choose. Consider the following factors:
Standard Turnaround Time: Most labs quote a standard turnaround time. That window shifts with the lab’s workload. It also shifts with how complex the calibration is. Make sure the standard time fits your schedule.
Expedited Services: Some labs offer rush service for an added fee. You may need faster turnaround. You may have an urgent job. Ask about the cost and the availability of rush work.
Communication: Clear updates keep expectations in line with reality. Choose a lab that tells you where your order stands. Good updates help you plan. They also cut downtime.
Do They Offer Pickup and Delivery?
Convenience is a significant consideration when selecting a calibration lab. Inquire whether the lab offers pickup and delivery services for your equipment. Here are some points to consider:
Service Area: Check whether pickup and delivery covers your area. Some labs serve only a set radius. Others ship across the country or overseas.
Cost and Timing: Ask what pickup and delivery costs. Ask how it affects your schedule. Weigh both in your decision. This matters most if you are in a remote area or need frequent calibrations.
Does the calibration lab provide onsite calibration?
In certain situations, onsite calibration may be preferable or necessary. Here are some factors to consider regarding onsite calibration services:
Minimize Downtime: Onsite calibration cuts downtime. Your equipment never leaves the floor. Ask yourself whether your operation can afford to ship gear off-site and wait.
Equipment Accessibility: Some gear is hard or impractical to move. Onsite calibration is the clear choice there. Check that the lab has the skill and the standards to work on your instruments in place.
Cost and Availability: Onsite work can cost more than lab work. Compare that cost against the value it returns. Then check that the lab has openings when you need them.
