I have a hand compass that need calibration.   It's manufactured by Saura and it's model number is HB-65G.   Does anyone know who can calibrate this for me?   Thanks

Is this a needle type?  Comparison with a known good compass would be good on this.   If its digital, then you might try the manufacturer.

I have had luck with Warren Knight industries...turn time sucks but price is not bad.

If you still need it calibrated, send to Instrument Repair and Calibration in Houston, Texas. Excellent service 3-5 day turn around and they also include at no extra charge before and after data on all units that complies with ANCI Z540 and ISO. i wanna say it was around 75.00-85.00 and with the data (we are REQUIRED by ISO) great service and resonable. Also, they send us a "recall notice" that my unit is about to be out of cal as a reminder. VERY helpful when you have 100+ units that are due at any giving time. Be interested to know how it comes out. Good luck.

I need a calibration source for 2 MKS 627B manometers. I have a 1000 Torr head and a 0.1 Torr head. I need a source for NIST traceable calibration of these items. Accreditation would be nice, but not required for this project. If you are a commercial lab with this capability please PM me. If you know of a commercial source for these items let me know also. The turn around time at MKS is beyond ridiculous.

My system is not currently calibrated at the moment, or I would say to send them to me.  I do from 0.1 through 1000 Torr Baratrons.  Fluke (former DH Instruments) in Phoenix does my Baratrons and have done a good job with them.  Other than that, MKS in Dallas could do them if you need a basic calibration.  Due to some recent transitions, my system which has been online, cal'd and in use has been temporarily deferred (expensive to get the system calibrated).  Maybe by next year I'll be up and running.

Compass calibration: we had a Theodolite, we survey two pedestals, one for the theodolite and the other for a target, we adjust the scale on the theodolite to the target (pedestal) value then put the compass on top of the theodolite and rotated the theodolite to point the same way the compass pointed. Then compared compass and theodolite values,

MKS, in spite of their poor turnaround time, is about half the cost of Danaher/Fluke/DH Instruments. I have a cal system with 3 MKS 690 secondary standards (.1 to 1000 torr). Keeping it calibrated is indeed expensive.

I would make sure the company can actually calibrate the compass. It's not unheard of for some unscrupulous lab managers to claim they can cal "anything", and then lick and stick...I've seen it first hand.  If they're legit, they wont have any problem telling you how they plan on calibrating the compass....and what standards they will use.

Just be cautious of the labs that claim they can cal 
"anything". Let them prove to you they can do what they promise. It pays to be skeptical...

oh no, I just noticed that the original post is from 3 years ago, I hope by now they already got it calibrated.
