Y’all do a great job


In 2018 when I was looking for a calibration service provider I reached out to several services the only company that responded swiftly was this one (formerly JA King). I scheduled them and got my calibrations started. The competitors that finally did respond were more expensive and less professional. My interactions with this company in the 3.5 years since has been exceptional. Your staff is friendly and helpful. They always respond quickly and professionally. I appreciate all of you.

My company has used several different calibration companies over the past 13 year. J.A. King (now Cross Precision) at the Bessemer (Birmingham) location is by far the absolute best. The staff is great, knowledgably, and friendly. Turn around time and reliability is fantastic.

Did you know... the precision measurement group at Cross was founded in 1939 by our current CEO's grandfather, Jim King. That's a whole lot of calibration!
Did you know... A fingerprint weighs about 50 micrograms. We know, we weighed it! The residue left from a finger can actually make a difference in weight results which is why we wear gloves when we calibrate weights. For reference, a sheet to paper is about 4.5 grams, that’s 4.5 million micrograms.
Did you know… Cross Company is an ESOP (Employee Stock Ownership Plan). Our ESOP started in 1979 and as of 2006, we are a 100% employee owned! Learn more about our ESOP and how that benefits both team members and our customers.
