They can provide tracibility for absolutely no extra charge. ?All they need to do is list the equipment used and the recall date. ?IF they are a legit Cal Lab all of their equipment is calibrated, some internally some externally and records are maintained. ?They use the same equipment to ¡°cal¡± your equipment wether they write a cert. or not.
If they don¡¯t supply a cert. as part of the job find a new lab that does.
Running a cal facility REQUIRES that you do certain things of you don¡¯t you are not a cal lab
Just my two cents.?

?Most places will give you traceability but charge extra for it. That's not as crappy as it sounds, if you think about it...If you don't need traceability for legal or contractual reasons, but just want to take good measurements, you can get what you want a bit cheaper. ?Lots and lots of companies do it that way, including Keysight, as you observed. ??????????????-DaveOn 2/27/21 3:39 PM, Steve - Home wrote:True, but you¡¯d think if they have traceability they¡¯d mention it on the certificate. Unless they do a tiered pricing like HPAK. One price for a ¡°bare bones¡± cal, slighter higher for cal with more data, much higher for cal with overall uncertainties, etc.

No evidence their calibration is traceable to any national standards...

?Parkertest is a seller on ebay, I also posted a link to their D&B stats - seem to be a real business.
I'm attaching a picture of the certificate they supply with a calibration.
Cheers!

Parkertest will rebuild the sensor and provide a certificate of
calibration equal to new.
What is a "Parkertest?" ... there are several interpretations of that based on Google.
Does "Parkertest" refer to an Ebay entity?
I'm not saying "Parkertest" ... as referenced in Bruce's post... can't/won't/doesn't provide a "... certificate of calibration equal to new." But, how do we know "Parkertest" does?
